Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458536, here are decompositions:

157 + 31458379 = 31458536
163 + 31458373 = 31458536
349 + 31458187 = 31458536
367 + 31458169 = 31458536
523 + 31458013 = 31458536
547 + 31457989 = 31458536
607 + 31457929 = 31458536
829 + 31457707 = 31458536

Showing the first eight; more decompositions exist.
