Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534760, here are decompositions:

3 + 31534757 = 31534760
7 + 31534753 = 31534760
31 + 31534729 = 31534760
109 + 31534651 = 31534760
163 + 31534597 = 31534760
199 + 31534561 = 31534760
277 + 31534483 = 31534760
331 + 31534429 = 31534760

Showing the first eight; more decompositions exist.
