Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600954, here are decompositions:

71 + 31600883 = 31600954
131 + 31600823 = 31600954
137 + 31600817 = 31600954
233 + 31600721 = 31600954
251 + 31600703 = 31600954
431 + 31600523 = 31600954
443 + 31600511 = 31600954
461 + 31600493 = 31600954

Showing the first eight; more decompositions exist.
