Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614550, here are decompositions:

3 + 31614547 = 31614550
101 + 31614449 = 31614550
173 + 31614377 = 31614550
179 + 31614371 = 31614550
197 + 31614353 = 31614550
353 + 31614197 = 31614550
389 + 31614161 = 31614550
479 + 31614071 = 31614550

Showing the first eight; more decompositions exist.
