Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31591762, here are decompositions:

11 + 31591751 = 31591762
23 + 31591739 = 31591762
29 + 31591733 = 31591762
113 + 31591649 = 31591762
263 + 31591499 = 31591762
269 + 31591493 = 31591762
353 + 31591409 = 31591762
431 + 31591331 = 31591762

Showing the first eight; more decompositions exist.
