Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31591652, here are decompositions:

3 + 31591649 = 31591652
139 + 31591513 = 31591652
199 + 31591453 = 31591652
271 + 31591381 = 31591652
643 + 31591009 = 31591652
661 + 31590991 = 31591652
709 + 31590943 = 31591652
811 + 31590841 = 31591652

Showing the first eight; more decompositions exist.
