Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480532, here are decompositions:

3 + 31480529 = 31480532
151 + 31480381 = 31480532
163 + 31480369 = 31480532
331 + 31480201 = 31480532
571 + 31479961 = 31480532
739 + 31479793 = 31480532
883 + 31479649 = 31480532
991 + 31479541 = 31480532

Showing the first eight; more decompositions exist.
