Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480292, here are decompositions:

3 + 31480289 = 31480292
163 + 31480129 = 31480292
271 + 31480021 = 31480292
331 + 31479961 = 31480292
463 + 31479829 = 31480292
499 + 31479793 = 31480292
523 + 31479769 = 31480292
643 + 31479649 = 31480292

Showing the first eight; more decompositions exist.
