Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458624, here are decompositions:

17 + 31458607 = 31458624
23 + 31458601 = 31458624
31 + 31458593 = 31458624
37 + 31458587 = 31458624
83 + 31458541 = 31458624
97 + 31458527 = 31458624
137 + 31458487 = 31458624
173 + 31458451 = 31458624

Showing the first eight; more decompositions exist.
