Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549060, here are decompositions:

17 + 31549043 = 31549060
41 + 31549019 = 31549060
107 + 31548953 = 31549060
293 + 31548767 = 31549060
311 + 31548749 = 31549060
317 + 31548743 = 31549060
383 + 31548677 = 31549060
401 + 31548659 = 31549060

Showing the first eight; more decompositions exist.
