Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480354, here are decompositions:

5 + 31480349 = 31480354
251 + 31480103 = 31480354
263 + 31480091 = 31480354
293 + 31480061 = 31480354
617 + 31479737 = 31480354
683 + 31479671 = 31480354
761 + 31479593 = 31480354
797 + 31479557 = 31480354

Showing the first eight; more decompositions exist.
