Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595672, here are decompositions:

19 + 31595653 = 31595672
61 + 31595611 = 31595672
79 + 31595593 = 31595672
103 + 31595569 = 31595672
421 + 31595251 = 31595672
463 + 31595209 = 31595672
499 + 31595173 = 31595672
571 + 31595101 = 31595672

Showing the first eight; more decompositions exist.
