Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444850, here are decompositions:

7 + 31444843 = 31444850
13 + 31444837 = 31444850
37 + 31444813 = 31444850
43 + 31444807 = 31444850
61 + 31444789 = 31444850
79 + 31444771 = 31444850
127 + 31444723 = 31444850
223 + 31444627 = 31444850

Showing the first eight; more decompositions exist.
