Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612452, here are decompositions:

23 + 31612429 = 31612452
29 + 31612423 = 31612452
61 + 31612391 = 31612452
71 + 31612381 = 31612452
83 + 31612369 = 31612452
89 + 31612363 = 31612452
101 + 31612351 = 31612452
139 + 31612313 = 31612452

Showing the first eight; more decompositions exist.
