Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506110, here are decompositions:

7 + 31506103 = 31506110
19 + 31506091 = 31506110
79 + 31506031 = 31506110
127 + 31505983 = 31506110
151 + 31505959 = 31506110
373 + 31505737 = 31506110
379 + 31505731 = 31506110
409 + 31505701 = 31506110

Showing the first eight; more decompositions exist.
