Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608292, here are decompositions:

29 + 31608263 = 31608292
251 + 31608041 = 31608292
263 + 31608029 = 31608292
383 + 31607909 = 31608292
389 + 31607903 = 31608292
461 + 31607831 = 31608292
503 + 31607789 = 31608292
509 + 31607783 = 31608292

Showing the first eight; more decompositions exist.
