Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450050, here are decompositions:

7 + 31450043 = 31450050
17 + 31450033 = 31450050
19 + 31450031 = 31450050
29 + 31450021 = 31450050
59 + 31449991 = 31450050
61 + 31449989 = 31450050
83 + 31449967 = 31450050
113 + 31449937 = 31450050

Showing the first eight; more decompositions exist.
