Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601182, here are decompositions:

3 + 31601179 = 31601182
83 + 31601099 = 31601182
131 + 31601051 = 31601182
359 + 31600823 = 31601182
383 + 31600799 = 31601182
449 + 31600733 = 31601182
461 + 31600721 = 31601182
479 + 31600703 = 31601182

Showing the first eight; more decompositions exist.
