Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458496, here are decompositions:

59 + 31458437 = 31458496
197 + 31458299 = 31458496
257 + 31458239 = 31458496
383 + 31458113 = 31458496
593 + 31457903 = 31458496
647 + 31457849 = 31458496
653 + 31457843 = 31458496
677 + 31457819 = 31458496

Showing the first eight; more decompositions exist.
