Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482974, here are decompositions:

67 + 31482907 = 31482974
151 + 31482823 = 31482974
307 + 31482667 = 31482974
331 + 31482643 = 31482974
463 + 31482511 = 31482974
547 + 31482427 = 31482974
631 + 31482343 = 31482974
727 + 31482247 = 31482974

Showing the first eight; more decompositions exist.
