Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610864, here are decompositions:

73 + 31610791 = 31610864
157 + 31610707 = 31610864
223 + 31610641 = 31610864
277 + 31610587 = 31610864
283 + 31610581 = 31610864
547 + 31610317 = 31610864
577 + 31610287 = 31610864
751 + 31610113 = 31610864

Showing the first eight; more decompositions exist.
