Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498712, here are decompositions:

73 + 31498639 = 31498712
163 + 31498549 = 31498712
199 + 31498513 = 31498712
241 + 31498471 = 31498712
433 + 31498279 = 31498712
439 + 31498273 = 31498712
499 + 31498213 = 31498712
523 + 31498189 = 31498712

Showing the first eight; more decompositions exist.
