Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480094, here are decompositions:

3 + 31480091 = 31480094
73 + 31480021 = 31480094
277 + 31479817 = 31480094
337 + 31479757 = 31480094
397 + 31479697 = 31480094
577 + 31479517 = 31480094
673 + 31479421 = 31480094
757 + 31479337 = 31480094

Showing the first eight; more decompositions exist.
