Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454862, here are decompositions:

53 + 31454809 = 31454862
79 + 31454783 = 31454862
181 + 31454681 = 31454862
193 + 31454669 = 31454862
211 + 31454651 = 31454862
349 + 31454513 = 31454862
379 + 31454483 = 31454862
401 + 31454461 = 31454862

Showing the first eight; more decompositions exist.
