Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574266, here are decompositions:

5 + 31574261 = 31574266
167 + 31574099 = 31574266
173 + 31574093 = 31574266
419 + 31573847 = 31574266
443 + 31573823 = 31574266
509 + 31573757 = 31574266
569 + 31573697 = 31574266
587 + 31573679 = 31574266

Showing the first eight; more decompositions exist.
