Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615954, here are decompositions:

3 + 31615951 = 31615954
107 + 31615847 = 31615954
191 + 31615763 = 31615954
197 + 31615757 = 31615954
563 + 31615391 = 31615954
641 + 31615313 = 31615954
743 + 31615211 = 31615954
761 + 31615193 = 31615954

Showing the first eight; more decompositions exist.
