Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519598, here are decompositions:

31 + 31519567 = 31519598
67 + 31519531 = 31519598
79 + 31519519 = 31519598
139 + 31519459 = 31519598
157 + 31519441 = 31519598
181 + 31519417 = 31519598
241 + 31519357 = 31519598
277 + 31519321 = 31519598

Showing the first eight; more decompositions exist.
