Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614636, here are decompositions:

5 + 31614631 = 31614636
73 + 31614563 = 31614636
89 + 31614547 = 31614636
113 + 31614523 = 31614636
283 + 31614353 = 31614636
293 + 31614343 = 31614636
353 + 31614283 = 31614636
359 + 31614277 = 31614636

Showing the first eight; more decompositions exist.
