Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519446, here are decompositions:

5 + 31519441 = 31519446
19 + 31519427 = 31519446
29 + 31519417 = 31519446
43 + 31519403 = 31519446
67 + 31519379 = 31519446
83 + 31519363 = 31519446
89 + 31519357 = 31519446
139 + 31519307 = 31519446

Showing the first eight; more decompositions exist.
