Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595906, here are decompositions:

37 + 31595869 = 31595906
73 + 31595833 = 31595906
313 + 31595593 = 31595906
337 + 31595569 = 31595906
439 + 31595467 = 31595906
499 + 31595407 = 31595906
523 + 31595383 = 31595906
733 + 31595173 = 31595906

Showing the first eight; more decompositions exist.
