Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452974, here are decompositions:

31 + 31452943 = 31452974
73 + 31452901 = 31452974
181 + 31452793 = 31452974
211 + 31452763 = 31452974
307 + 31452667 = 31452974
367 + 31452607 = 31452974
457 + 31452517 = 31452974
523 + 31452451 = 31452974

Showing the first eight; more decompositions exist.
