Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498448, here are decompositions:

337 + 31498111 = 31498448
379 + 31498069 = 31498448
409 + 31498039 = 31498448
439 + 31498009 = 31498448
577 + 31497871 = 31498448
691 + 31497757 = 31498448
727 + 31497721 = 31498448
769 + 31497679 = 31498448

Showing the first eight; more decompositions exist.
