Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619342, here are decompositions:

31 + 31619311 = 31619342
61 + 31619281 = 31619342
151 + 31619191 = 31619342
163 + 31619179 = 31619342
199 + 31619143 = 31619342
463 + 31618879 = 31619342
523 + 31618819 = 31619342
571 + 31618771 = 31619342

Showing the first eight; more decompositions exist.
