Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458462, here are decompositions:

11 + 31458451 = 31458462
31 + 31458431 = 31458462
43 + 31458419 = 31458462
59 + 31458403 = 31458462
83 + 31458379 = 31458462
89 + 31458373 = 31458462
131 + 31458331 = 31458462
151 + 31458311 = 31458462

Showing the first eight; more decompositions exist.
