Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595426, here are decompositions:

19 + 31595407 = 31595426
43 + 31595383 = 31595426
367 + 31595059 = 31595426
439 + 31594987 = 31595426
463 + 31594963 = 31595426
523 + 31594903 = 31595426
613 + 31594813 = 31595426
619 + 31594807 = 31595426

Showing the first eight; more decompositions exist.
