Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506152, here are decompositions:

3 + 31506149 = 31506152
61 + 31506091 = 31506152
163 + 31505989 = 31506152
193 + 31505959 = 31506152
229 + 31505923 = 31506152
331 + 31505821 = 31506152
421 + 31505731 = 31506152
619 + 31505533 = 31506152

Showing the first eight; more decompositions exist.
