Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612992, here are decompositions:

23 + 8612969 = 8612992
131 + 8612861 = 8612992
191 + 8612801 = 8612992
239 + 8612753 = 8612992
263 + 8612729 = 8612992
281 + 8612711 = 8612992
359 + 8612633 = 8612992
461 + 8612531 = 8612992

Showing the first eight; more decompositions exist.
