Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480004, here are decompositions:

43 + 31479961 = 31480004
211 + 31479793 = 31480004
307 + 31479697 = 31480004
463 + 31479541 = 31480004
487 + 31479517 = 31480004
547 + 31479457 = 31480004
727 + 31479277 = 31480004
733 + 31479271 = 31480004

Showing the first eight; more decompositions exist.
