Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574012, here are decompositions:

13 + 31573999 = 31574012
181 + 31573831 = 31574012
193 + 31573819 = 31574012
373 + 31573639 = 31574012
499 + 31573513 = 31574012
619 + 31573393 = 31574012
733 + 31573279 = 31574012
751 + 31573261 = 31574012

Showing the first eight; more decompositions exist.
