Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454992, here are decompositions:

83 + 31454909 = 31454992
89 + 31454903 = 31454992
251 + 31454741 = 31454992
311 + 31454681 = 31454992
479 + 31454513 = 31454992
509 + 31454483 = 31454992
641 + 31454351 = 31454992
743 + 31454249 = 31454992

Showing the first eight; more decompositions exist.
