Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483850, here are decompositions:

31 + 31483819 = 31483850
43 + 31483807 = 31483850
61 + 31483789 = 31483850
127 + 31483723 = 31483850
379 + 31483471 = 31483850
397 + 31483453 = 31483850
421 + 31483429 = 31483850
499 + 31483351 = 31483850

Showing the first eight; more decompositions exist.
