Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595750, here are decompositions:

19 + 31595731 = 31595750
31 + 31595719 = 31595750
79 + 31595671 = 31595750
97 + 31595653 = 31595750
139 + 31595611 = 31595750
157 + 31595593 = 31595750
181 + 31595569 = 31595750
283 + 31595467 = 31595750

Showing the first eight; more decompositions exist.
