Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533702, here are decompositions:

41 + 31533661 = 31533702
43 + 31533659 = 31533702
61 + 31533641 = 31533702
71 + 31533631 = 31533702
89 + 31533613 = 31533702
103 + 31533599 = 31533702
131 + 31533571 = 31533702
139 + 31533563 = 31533702

Showing the first eight; more decompositions exist.
