Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497318, here are decompositions:

  • 347 + 2147496971 = 2147497318
  • 401 + 2147496917 = 2147497318
  • 479 + 2147496839 = 2147497318
  • 587 + 2147496731 = 2147497318
  • 761 + 2147496557 = 2147497318
  • 839 + 2147496479 = 2147497318
  • 881 + 2147496437 = 2147497318
  • 887 + 2147496431 = 2147497318

Showing the first eight; more decompositions exist.
