Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480244, here are decompositions:

43 + 31480201 = 31480244
127 + 31480117 = 31480244
223 + 31480021 = 31480244
283 + 31479961 = 31480244
487 + 31479757 = 31480244
547 + 31479697 = 31480244
727 + 31479517 = 31480244
787 + 31479457 = 31480244

Showing the first eight; more decompositions exist.
