Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516598, here are decompositions:

31 + 31516567 = 31516598
79 + 31516519 = 31516598
97 + 31516501 = 31516598
241 + 31516357 = 31516598
271 + 31516327 = 31516598
397 + 31516201 = 31516598
409 + 31516189 = 31516598
439 + 31516159 = 31516598

Showing the first eight; more decompositions exist.
