Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450084, here are decompositions:

23 + 31450061 = 31450084
41 + 31450043 = 31450084
53 + 31450031 = 31450084
293 + 31449791 = 31450084
317 + 31449767 = 31450084
383 + 31449701 = 31450084
503 + 31449581 = 31450084
557 + 31449527 = 31450084

Showing the first eight; more decompositions exist.
