Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147561098, here are decompositions:

  • 149 + 2147560949 = 2147561098
  • 251 + 2147560847 = 2147561098
  • 281 + 2147560817 = 2147561098
  • 461 + 2147560637 = 2147561098
  • 509 + 2147560589 = 2147561098
  • 587 + 2147560511 = 2147561098
  • 647 + 2147560451 = 2147561098
  • 719 + 2147560379 = 2147561098

Showing the first eight; more decompositions exist.
