Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448226, here are decompositions:

157 + 31448069 = 31448226
193 + 31448033 = 31448226
239 + 31447987 = 31448226
263 + 31447963 = 31448226
269 + 31447957 = 31448226
373 + 31447853 = 31448226
389 + 31447837 = 31448226
443 + 31447783 = 31448226

Showing the first eight; more decompositions exist.
