Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480946, here are decompositions:

67 + 31480879 = 31480946
73 + 31480873 = 31480946
97 + 31480849 = 31480946
307 + 31480639 = 31480946
439 + 31480507 = 31480946
577 + 31480369 = 31480946
829 + 31480117 = 31480946
997 + 31479949 = 31480946

Showing the first eight; more decompositions exist.
