Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102480, here are decompositions:

  • 19 + 102461 = 102480
  • 29 + 102451 = 102480
  • 43 + 102437 = 102480
  • 47 + 102433 = 102480
  • 71 + 102409 = 102480
  • 73 + 102407 = 102480
  • 83 + 102397 = 102480
  • 113 + 102367 = 102480

Showing the first eight; more decompositions exist.
