Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480982, here are decompositions:

19 + 31480963 = 31480982
103 + 31480879 = 31480982
109 + 31480873 = 31480982
541 + 31480441 = 31480982
601 + 31480381 = 31480982
613 + 31480369 = 31480982
853 + 31480129 = 31480982
1021 + 31479961 = 31480982

Showing the first eight; more decompositions exist.
