Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450862, here are decompositions:

19 + 31450843 = 31450862
61 + 31450801 = 31450862
73 + 31450789 = 31450862
139 + 31450723 = 31450862
241 + 31450621 = 31450862
283 + 31450579 = 31450862
379 + 31450483 = 31450862
433 + 31450429 = 31450862

Showing the first eight; more decompositions exist.
