Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574224, here are decompositions:

23 + 31574201 = 31574224
131 + 31574093 = 31574224
257 + 31573967 = 31574224
263 + 31573961 = 31574224
293 + 31573931 = 31574224
401 + 31573823 = 31574224
431 + 31573793 = 31574224
467 + 31573757 = 31574224

Showing the first eight; more decompositions exist.
