Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574226, here are decompositions:

23 + 31574203 = 31574226
53 + 31574173 = 31574226
127 + 31574099 = 31574226
179 + 31574047 = 31574226
227 + 31573999 = 31574226
269 + 31573957 = 31574226
367 + 31573859 = 31574226
373 + 31573853 = 31574226

Showing the first eight; more decompositions exist.
