Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147384788, here are decompositions:

  • 41 + 2147384747 = 2147384788
  • 167 + 2147384621 = 2147384788
  • 179 + 2147384609 = 2147384788
  • 251 + 2147384537 = 2147384788
  • 401 + 2147384387 = 2147384788
  • 587 + 2147384201 = 2147384788
  • 677 + 2147384111 = 2147384788
  • 761 + 2147384027 = 2147384788

Showing the first eight; more decompositions exist.
