Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506662, here are decompositions:

139 + 31506523 = 31506662
151 + 31506511 = 31506662
241 + 31506421 = 31506662
331 + 31506331 = 31506662
379 + 31506283 = 31506662
571 + 31506091 = 31506662
601 + 31506061 = 31506662
631 + 31506031 = 31506662

Showing the first eight; more decompositions exist.
