Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595722, here are decompositions:

3 + 31595719 = 31595722
5 + 31595717 = 31595722
149 + 31595573 = 31595722
239 + 31595483 = 31595722
359 + 31595363 = 31595722
443 + 31595279 = 31595722
449 + 31595273 = 31595722
479 + 31595243 = 31595722

Showing the first eight; more decompositions exist.
