Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506594, here are decompositions:

17 + 31506577 = 31506594
71 + 31506523 = 31506594
73 + 31506521 = 31506594
83 + 31506511 = 31506594
151 + 31506443 = 31506594
157 + 31506437 = 31506594
173 + 31506421 = 31506594
227 + 31506367 = 31506594

Showing the first eight; more decompositions exist.
