Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627298, here are decompositions:

37 + 31627261 = 31627298
61 + 31627237 = 31627298
97 + 31627201 = 31627298
229 + 31627069 = 31627298
271 + 31627027 = 31627298
331 + 31626967 = 31627298
457 + 31626841 = 31627298
607 + 31626691 = 31627298

Showing the first eight; more decompositions exist.
