Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480362, here are decompositions:

13 + 31480349 = 31480362
73 + 31480289 = 31480362
103 + 31480259 = 31480362
233 + 31480129 = 31480362
271 + 31480091 = 31480362
283 + 31480079 = 31480362
313 + 31480049 = 31480362
401 + 31479961 = 31480362

Showing the first eight; more decompositions exist.
