Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595624, here are decompositions:

13 + 31595611 = 31595624
31 + 31595593 = 31595624
43 + 31595581 = 31595624
157 + 31595467 = 31595624
241 + 31595383 = 31595624
373 + 31595251 = 31595624
523 + 31595101 = 31595624
661 + 31594963 = 31595624

Showing the first eight; more decompositions exist.
