Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480850, here are decompositions:

157 + 31480693 = 31480850
211 + 31480639 = 31480850
229 + 31480621 = 31480850
409 + 31480441 = 31480850
733 + 31480117 = 31480850
829 + 31480021 = 31480850
1021 + 31479829 = 31480850
1033 + 31479817 = 31480850

Showing the first eight; more decompositions exist.
