Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480484, here are decompositions:

43 + 31480441 = 31480484
103 + 31480381 = 31480484
283 + 31480201 = 31480484
367 + 31480117 = 31480484
463 + 31480021 = 31480484
523 + 31479961 = 31480484
691 + 31479793 = 31480484
727 + 31479757 = 31480484

Showing the first eight; more decompositions exist.
