Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607030, here are decompositions:

67 + 31606963 = 31607030
73 + 31606957 = 31607030
79 + 31606951 = 31607030
127 + 31606903 = 31607030
151 + 31606879 = 31607030
277 + 31606753 = 31607030
349 + 31606681 = 31607030
373 + 31606657 = 31607030

Showing the first eight; more decompositions exist.
