Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610486, here are decompositions:

73 + 31610413 = 31610486
97 + 31610389 = 31610486
199 + 31610287 = 31610486
373 + 31610113 = 31610486
379 + 31610107 = 31610486
463 + 31610023 = 31610486
673 + 31609813 = 31610486
709 + 31609777 = 31610486

Showing the first eight; more decompositions exist.
