Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574492, here are decompositions:

3 + 31574489 = 31574492
13 + 31574479 = 31574492
43 + 31574449 = 31574492
73 + 31574419 = 31574492
163 + 31574329 = 31574492
421 + 31574071 = 31574492
661 + 31573831 = 31574492
673 + 31573819 = 31574492

Showing the first eight; more decompositions exist.
