Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506234, here are decompositions:

41 + 31506193 = 31506234
61 + 31506173 = 31506234
131 + 31506103 = 31506234
163 + 31506071 = 31506234
173 + 31506061 = 31506234
241 + 31505993 = 31506234
251 + 31505983 = 31506234
307 + 31505927 = 31506234

Showing the first eight; more decompositions exist.
