Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574062, here are decompositions:

41 + 31574021 = 31574062
101 + 31573961 = 31574062
131 + 31573931 = 31574062
239 + 31573823 = 31574062
269 + 31573793 = 31574062
383 + 31573679 = 31574062
419 + 31573643 = 31574062
479 + 31573583 = 31574062

Showing the first eight; more decompositions exist.
