Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593626, here are decompositions:

13 + 31593613 = 31593626
19 + 31593607 = 31593626
37 + 31593589 = 31593626
73 + 31593553 = 31593626
109 + 31593517 = 31593626
283 + 31593343 = 31593626
313 + 31593313 = 31593626
373 + 31593253 = 31593626

Showing the first eight; more decompositions exist.
