Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747380, here are decompositions:

  • 53 + 8747327 = 8747380
  • 107 + 8747273 = 8747380
  • 137 + 8747243 = 8747380
  • 167 + 8747213 = 8747380
  • 269 + 8747111 = 8747380
  • 401 + 8746979 = 8747380
  • 431 + 8746949 = 8747380
  • 443 + 8746937 = 8747380

Showing the first eight; more decompositions exist.
