Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458364, here are decompositions:

53 + 31458311 = 31458364
167 + 31458197 = 31458364
173 + 31458191 = 31458364
191 + 31458173 = 31458364
233 + 31458131 = 31458364
251 + 31458113 = 31458364
281 + 31458083 = 31458364
461 + 31457903 = 31458364

Showing the first eight; more decompositions exist.
