Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480964, here are decompositions:

103 + 31480861 = 31480964
271 + 31480693 = 31480964
283 + 31480681 = 31480964
457 + 31480507 = 31480964
523 + 31480441 = 31480964
1171 + 31479793 = 31480964
1423 + 31479541 = 31480964
1447 + 31479517 = 31480964

Showing the first eight; more decompositions exist.
