Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15380, here are decompositions:

  • 3 + 15377 = 15380
  • 7 + 15373 = 15380
  • 19 + 15361 = 15380
  • 31 + 15349 = 15380
  • 61 + 15319 = 15380
  • 67 + 15313 = 15380
  • 73 + 15307 = 15380
  • 103 + 15277 = 15380

Showing the first eight; more decompositions exist.
