Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474448, here are decompositions:

  • 97 + 31474351 = 31474448
  • 157 + 31474291 = 31474448
  • 199 + 31474249 = 31474448
  • 277 + 31474171 = 31474448
  • 307 + 31474141 = 31474448
  • 337 + 31474111 = 31474448
  • 457 + 31473991 = 31474448
  • 541 + 31473907 = 31474448

Showing the first eight; more decompositions exist.
