Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450676, here are decompositions:

73 + 31450603 = 31450676
97 + 31450579 = 31450676
193 + 31450483 = 31450676
307 + 31450369 = 31450676
457 + 31450219 = 31450676
577 + 31450099 = 31450676
619 + 31450057 = 31450676
643 + 31450033 = 31450676

Showing the first eight; more decompositions exist.
