Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450032, here are decompositions:

11 + 31450021 = 31450032
41 + 31449991 = 31450032
43 + 31449989 = 31450032
101 + 31449931 = 31450032
109 + 31449923 = 31450032
179 + 31449853 = 31450032
241 + 31449791 = 31450032
281 + 31449751 = 31450032

Showing the first eight; more decompositions exist.
