Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458622, here are decompositions:

29 + 31458593 = 31458622
191 + 31458431 = 31458622
311 + 31458311 = 31458622
383 + 31458239 = 31458622
431 + 31458191 = 31458622
449 + 31458173 = 31458622
491 + 31458131 = 31458622
509 + 31458113 = 31458622

Showing the first eight; more decompositions exist.
