Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724248, here are decompositions:

  • 7 + 8724241 = 8724248
  • 67 + 8724181 = 8724248
  • 79 + 8724169 = 8724248
  • 109 + 8724139 = 8724248
  • 271 + 8723977 = 8724248
  • 349 + 8723899 = 8724248
  • 397 + 8723851 = 8724248
  • 541 + 8723707 = 8724248

Showing the first eight; more decompositions exist.
