Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497374, here are decompositions:

37 + 31497337 = 31497374
61 + 31497313 = 31497374
151 + 31497223 = 31497374
241 + 31497133 = 31497374
367 + 31497007 = 31497374
373 + 31497001 = 31497374
397 + 31496977 = 31497374
457 + 31496917 = 31497374

Showing the first eight; more decompositions exist.
