Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458694, here are decompositions:

5 + 31458689 = 31458694
101 + 31458593 = 31458694
107 + 31458587 = 31458694
167 + 31458527 = 31458694
257 + 31458437 = 31458694
263 + 31458431 = 31458694
317 + 31458377 = 31458694
383 + 31458311 = 31458694

Showing the first eight; more decompositions exist.
