Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494652, here are decompositions:

41 + 31494611 = 31494652
71 + 31494581 = 31494652
149 + 31494503 = 31494652
173 + 31494479 = 31494652
251 + 31494401 = 31494652
263 + 31494389 = 31494652
359 + 31494293 = 31494652
389 + 31494263 = 31494652

Showing the first eight; more decompositions exist.
