Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450444, here are decompositions:

17 + 31450427 = 31450444
23 + 31450421 = 31450444
131 + 31450313 = 31450444
173 + 31450271 = 31450444
197 + 31450247 = 31450444
227 + 31450217 = 31450444
281 + 31450163 = 31450444
383 + 31450061 = 31450444

Showing the first eight; more decompositions exist.
