Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450582, here are decompositions:

3 + 31450579 = 31450582
5 + 31450577 = 31450582
41 + 31450541 = 31450582
131 + 31450451 = 31450582
173 + 31450409 = 31450582
269 + 31450313 = 31450582
311 + 31450271 = 31450582
419 + 31450163 = 31450582

Showing the first eight; more decompositions exist.
