Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458562, here are decompositions:

131 + 31458431 = 31458562
251 + 31458311 = 31458562
263 + 31458299 = 31458562
389 + 31458173 = 31458562
431 + 31458131 = 31458562
449 + 31458113 = 31458562
479 + 31458083 = 31458562
563 + 31457999 = 31458562

Showing the first eight; more decompositions exist.
