Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619304, here are decompositions:

23 + 31619281 = 31619304
37 + 31619267 = 31619304
43 + 31619261 = 31619304
47 + 31619257 = 31619304
97 + 31619207 = 31619304
113 + 31619191 = 31619304
127 + 31619177 = 31619304
181 + 31619123 = 31619304

Showing the first eight; more decompositions exist.
