Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454810, here are decompositions:

73 + 31454737 = 31454810
109 + 31454701 = 31454810
157 + 31454653 = 31454810
223 + 31454587 = 31454810
313 + 31454497 = 31454810
349 + 31454461 = 31454810
379 + 31454431 = 31454810
421 + 31454389 = 31454810

Showing the first eight; more decompositions exist.
