Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506134, here are decompositions:

31 + 31506103 = 31506134
43 + 31506091 = 31506134
73 + 31506061 = 31506134
103 + 31506031 = 31506134
151 + 31505983 = 31506134
211 + 31505923 = 31506134
313 + 31505821 = 31506134
367 + 31505767 = 31506134

Showing the first eight; more decompositions exist.
