Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597214, here are decompositions:

37 + 31597177 = 31597214
163 + 31597051 = 31597214
211 + 31597003 = 31597214
223 + 31596991 = 31597214
307 + 31596907 = 31597214
331 + 31596883 = 31597214
367 + 31596847 = 31597214
421 + 31596793 = 31597214

Showing the first eight; more decompositions exist.
