Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458412, here are decompositions:

101 + 31458311 = 31458412
113 + 31458299 = 31458412
173 + 31458239 = 31458412
239 + 31458173 = 31458412
281 + 31458131 = 31458412
443 + 31457969 = 31458412
509 + 31457903 = 31458412
563 + 31457849 = 31458412

Showing the first eight; more decompositions exist.
