Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450976, here are decompositions:

79 + 31450897 = 31450976
97 + 31450879 = 31450976
373 + 31450603 = 31450976
397 + 31450579 = 31450976
433 + 31450543 = 31450976
547 + 31450429 = 31450976
607 + 31450369 = 31450976
757 + 31450219 = 31450976

Showing the first eight; more decompositions exist.
