Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519602, here are decompositions:

19 + 31519583 = 31519602
31 + 31519571 = 31519602
71 + 31519531 = 31519602
83 + 31519519 = 31519602
139 + 31519463 = 31519602
199 + 31519403 = 31519602
223 + 31519379 = 31519602
239 + 31519363 = 31519602

Showing the first eight; more decompositions exist.
