Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450844, here are decompositions:

3 + 31450841 = 31450844
43 + 31450801 = 31450844
223 + 31450621 = 31450844
241 + 31450603 = 31450844
421 + 31450423 = 31450844
433 + 31450411 = 31450844
457 + 31450387 = 31450844
727 + 31450117 = 31450844

Showing the first eight; more decompositions exist.
