Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590726, here are decompositions:

43 + 31590683 = 31590726
59 + 31590667 = 31590726
67 + 31590659 = 31590726
109 + 31590617 = 31590726
137 + 31590589 = 31590726
227 + 31590499 = 31590726
239 + 31590487 = 31590726
257 + 31590469 = 31590726

Showing the first eight; more decompositions exist.
