Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595792, here are decompositions:

61 + 31595731 = 31595792
73 + 31595719 = 31595792
139 + 31595653 = 31595792
181 + 31595611 = 31595792
199 + 31595593 = 31595792
211 + 31595581 = 31595792
223 + 31595569 = 31595792
409 + 31595383 = 31595792

Showing the first eight; more decompositions exist.
