Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563706, here are decompositions:

23 + 31563683 = 31563706
59 + 31563647 = 31563706
113 + 31563593 = 31563706
137 + 31563569 = 31563706
179 + 31563527 = 31563706
263 + 31563443 = 31563706
347 + 31563359 = 31563706
359 + 31563347 = 31563706

Showing the first eight; more decompositions exist.
