Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480838, here are decompositions:

157 + 31480681 = 31480838
199 + 31480639 = 31480838
331 + 31480507 = 31480838
397 + 31480441 = 31480838
457 + 31480381 = 31480838
709 + 31480129 = 31480838
877 + 31479961 = 31480838
1009 + 31479829 = 31480838

Showing the first eight; more decompositions exist.
