Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612722, here are decompositions:

59 + 31612663 = 31612722
61 + 31612661 = 31612722
101 + 31612621 = 31612722
103 + 31612619 = 31612722
139 + 31612583 = 31612722
149 + 31612573 = 31612722
191 + 31612531 = 31612722
241 + 31612481 = 31612722

Showing the first eight; more decompositions exist.
