Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506062, here are decompositions:

31 + 31506031 = 31506062
73 + 31505989 = 31506062
79 + 31505983 = 31506062
103 + 31505959 = 31506062
139 + 31505923 = 31506062
241 + 31505821 = 31506062
331 + 31505731 = 31506062
439 + 31505623 = 31506062

Showing the first eight; more decompositions exist.
