Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623564, here are decompositions:

41 + 31623523 = 31623564
43 + 31623521 = 31623564
53 + 31623511 = 31623564
67 + 31623497 = 31623564
73 + 31623491 = 31623564
83 + 31623481 = 31623564
103 + 31623461 = 31623564
191 + 31623373 = 31623564

Showing the first eight; more decompositions exist.
