Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612824, here are decompositions:

71 + 31612753 = 31612824
97 + 31612727 = 31612824
157 + 31612667 = 31612824
163 + 31612661 = 31612824
197 + 31612627 = 31612824
227 + 31612597 = 31612824
241 + 31612583 = 31612824
251 + 31612573 = 31612824

Showing the first eight; more decompositions exist.
