Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582126, here are decompositions:

5 + 31582121 = 31582126
29 + 31582097 = 31582126
83 + 31582043 = 31582126
89 + 31582037 = 31582126
179 + 31581947 = 31582126
263 + 31581863 = 31582126
347 + 31581779 = 31582126
419 + 31581707 = 31582126

Showing the first eight; more decompositions exist.
