Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449050, here are decompositions:

7 + 31449043 = 31449050
13 + 31449037 = 31449050
151 + 31448899 = 31449050
211 + 31448839 = 31449050
229 + 31448821 = 31449050
331 + 31448719 = 31449050
337 + 31448713 = 31449050
463 + 31448587 = 31449050

Showing the first eight; more decompositions exist.
