Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574006, here are decompositions:

7 + 31573999 = 31574006
367 + 31573639 = 31574006
379 + 31573627 = 31574006
613 + 31573393 = 31574006
643 + 31573363 = 31574006
727 + 31573279 = 31574006
853 + 31573153 = 31574006
883 + 31573123 = 31574006

Showing the first eight; more decompositions exist.
