Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450152, here are decompositions:

11 + 31450141 = 31450152
53 + 31450099 = 31450152
59 + 31450093 = 31450152
109 + 31450043 = 31450152
131 + 31450021 = 31450152
163 + 31449989 = 31450152
229 + 31449923 = 31450152
281 + 31449871 = 31450152

Showing the first eight; more decompositions exist.
