Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506266, here are decompositions:

3 + 31506263 = 31506266
19 + 31506247 = 31506266
73 + 31506193 = 31506266
163 + 31506103 = 31506266
277 + 31505989 = 31506266
283 + 31505983 = 31506266
307 + 31505959 = 31506266
457 + 31505809 = 31506266

Showing the first eight; more decompositions exist.
