Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519604, here are decompositions:

3 + 31519601 = 31519604
37 + 31519567 = 31519604
73 + 31519531 = 31519604
97 + 31519507 = 31519604
163 + 31519441 = 31519604
223 + 31519381 = 31519604
241 + 31519363 = 31519604
283 + 31519321 = 31519604

Showing the first eight; more decompositions exist.
