Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619294, here are decompositions:

13 + 31619281 = 31619294
37 + 31619257 = 31619294
103 + 31619191 = 31619294
151 + 31619143 = 31619294
277 + 31619017 = 31619294
313 + 31618981 = 31619294
397 + 31618897 = 31619294
523 + 31618771 = 31619294

Showing the first eight; more decompositions exist.
