Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450850, here are decompositions:

3 + 31450847 = 31450850
7 + 31450843 = 31450850
61 + 31450789 = 31450850
127 + 31450723 = 31450850
229 + 31450621 = 31450850
271 + 31450579 = 31450850
307 + 31450543 = 31450850
367 + 31450483 = 31450850

Showing the first eight; more decompositions exist.
