Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619204, here are decompositions:

13 + 31619191 = 31619204
61 + 31619143 = 31619204
163 + 31619041 = 31619204
223 + 31618981 = 31619204
307 + 31618897 = 31619204
313 + 31618891 = 31619204
433 + 31618771 = 31619204
523 + 31618681 = 31619204

Showing the first eight; more decompositions exist.
