Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498892, here are decompositions:

13 + 31498879 = 31498892
43 + 31498849 = 31498892
79 + 31498813 = 31498892
151 + 31498741 = 31498892
379 + 31498513 = 31498892
421 + 31498471 = 31498892
613 + 31498279 = 31498892
619 + 31498273 = 31498892

Showing the first eight; more decompositions exist.
