Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607102, here are decompositions:

139 + 31606963 = 31607102
151 + 31606951 = 31607102
199 + 31606903 = 31607102
223 + 31606879 = 31607102
349 + 31606753 = 31607102
421 + 31606681 = 31607102
523 + 31606579 = 31607102
673 + 31606429 = 31607102

Showing the first eight; more decompositions exist.
