Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489050, here are decompositions:

7 + 31489043 = 31489050
13 + 31489037 = 31489050
23 + 31489027 = 31489050
41 + 31489009 = 31489050
59 + 31488991 = 31489050
71 + 31488979 = 31489050
79 + 31488971 = 31489050
139 + 31488911 = 31489050

Showing the first eight; more decompositions exist.
