Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607174, here are decompositions:

37 + 31607137 = 31607174
73 + 31607101 = 31607174
127 + 31607047 = 31607174
211 + 31606963 = 31607174
223 + 31606951 = 31607174
271 + 31606903 = 31607174
421 + 31606753 = 31607174
433 + 31606741 = 31607174

Showing the first eight; more decompositions exist.
