Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448324, here are decompositions:

3 + 31448321 = 31448324
31 + 31448293 = 31448324
43 + 31448281 = 31448324
163 + 31448161 = 31448324
307 + 31448017 = 31448324
337 + 31447987 = 31448324
367 + 31447957 = 31448324
373 + 31447951 = 31448324

Showing the first eight; more decompositions exist.
