Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64786, here are decompositions:

3 + 64783 = 64786
5 + 64781 = 64786
23 + 64763 = 64786
107 + 64679 = 64786
173 + 64613 = 64786
233 + 64553 = 64786
347 + 64439 = 64786
353 + 64433 = 64786

Showing the first eight; more decompositions exist.
