Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612202, here are decompositions:

3 + 31612199 = 31612202
373 + 31611829 = 31612202
499 + 31611703 = 31612202
619 + 31611583 = 31612202
823 + 31611379 = 31612202
883 + 31611319 = 31612202
1039 + 31611163 = 31612202
1153 + 31611049 = 31612202

Showing the first eight; more decompositions exist.
