Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672428, here are decompositions:

  • 5 + 8672423 = 8672428
  • 41 + 8672387 = 8672428
  • 47 + 8672381 = 8672428
  • 131 + 8672297 = 8672428
  • 227 + 8672201 = 8672428
  • 251 + 8672177 = 8672428
  • 311 + 8672117 = 8672428
  • 449 + 8671979 = 8672428

Showing the first eight; more decompositions exist.
