Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595786, here are decompositions:

3 + 31595783 = 31595786
67 + 31595719 = 31595786
193 + 31595593 = 31595786
379 + 31595407 = 31595786
577 + 31595209 = 31595786
613 + 31595173 = 31595786
727 + 31595059 = 31595786
787 + 31594999 = 31595786

Showing the first eight; more decompositions exist.
