Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498592, here are decompositions:

43 + 31498549 = 31498592
79 + 31498513 = 31498592
313 + 31498279 = 31498592
379 + 31498213 = 31498592
523 + 31498069 = 31498592
613 + 31497979 = 31498592
661 + 31497931 = 31498592
709 + 31497883 = 31498592

Showing the first eight; more decompositions exist.
