Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574248, here are decompositions:

47 + 31574201 = 31574248
149 + 31574099 = 31574248
227 + 31574021 = 31574248
281 + 31573967 = 31574248
317 + 31573931 = 31574248
389 + 31573859 = 31574248
401 + 31573847 = 31574248
491 + 31573757 = 31574248

Showing the first eight; more decompositions exist.
