Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540708, here are decompositions:

29 + 31540679 = 31540708
71 + 31540637 = 31540708
179 + 31540529 = 31540708
467 + 31540241 = 31540708
491 + 31540217 = 31540708
599 + 31540109 = 31540708
677 + 31540031 = 31540708
701 + 31540007 = 31540708

Showing the first eight; more decompositions exist.
