Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480334, here are decompositions:

313 + 31480021 = 31480334
373 + 31479961 = 31480334
541 + 31479793 = 31480334
577 + 31479757 = 31480334
757 + 31479577 = 31480334
877 + 31479457 = 31480334
997 + 31479337 = 31480334
1063 + 31479271 = 31480334

Showing the first eight; more decompositions exist.
