Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595926, here are decompositions:

53 + 31595873 = 31595926
59 + 31595867 = 31595926
149 + 31595777 = 31595926
239 + 31595687 = 31595926
269 + 31595657 = 31595926
353 + 31595573 = 31595926
359 + 31595567 = 31595926
443 + 31595483 = 31595926

Showing the first eight; more decompositions exist.
