Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724370, here are decompositions:

  • 23 + 8724347 = 8724370
  • 41 + 8724329 = 8724370
  • 47 + 8724323 = 8724370
  • 59 + 8724311 = 8724370
  • 101 + 8724269 = 8724370
  • 107 + 8724263 = 8724370
  • 227 + 8724143 = 8724370
  • 269 + 8724101 = 8724370

Showing the first eight; more decompositions exist.
