Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595626, here are decompositions:

53 + 31595573 = 31595626
59 + 31595567 = 31595626
233 + 31595393 = 31595626
239 + 31595387 = 31595626
263 + 31595363 = 31595626
347 + 31595279 = 31595626
353 + 31595273 = 31595626
383 + 31595243 = 31595626

Showing the first eight; more decompositions exist.
