Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475526, here are decompositions:

37 + 31475489 = 31475526
67 + 31475459 = 31475526
73 + 31475453 = 31475526
83 + 31475443 = 31475526
97 + 31475429 = 31475526
139 + 31475387 = 31475526
239 + 31475287 = 31475526
283 + 31475243 = 31475526

Showing the first eight; more decompositions exist.
