Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506674, here are decompositions:

97 + 31506577 = 31506674
151 + 31506523 = 31506674
163 + 31506511 = 31506674
307 + 31506367 = 31506674
571 + 31506103 = 31506674
613 + 31506061 = 31506674
643 + 31506031 = 31506674
691 + 31505983 = 31506674

Showing the first eight; more decompositions exist.
