Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661236, here are decompositions:

  • 13 + 8661223 = 8661236
  • 19 + 8661217 = 8661236
  • 43 + 8661193 = 8661236
  • 193 + 8661043 = 8661236
  • 307 + 8660929 = 8661236
  • 349 + 8660887 = 8661236
  • 373 + 8660863 = 8661236
  • 439 + 8660797 = 8661236

Showing the first eight; more decompositions exist.
