Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480658, here are decompositions:

19 + 31480639 = 31480658
37 + 31480621 = 31480658
151 + 31480507 = 31480658
277 + 31480381 = 31480658
457 + 31480201 = 31480658
541 + 31480117 = 31480658
709 + 31479949 = 31480658
829 + 31479829 = 31480658

Showing the first eight; more decompositions exist.
