Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458654, here are decompositions:

11 + 31458643 = 31458654
23 + 31458631 = 31458654
47 + 31458607 = 31458654
53 + 31458601 = 31458654
61 + 31458593 = 31458654
67 + 31458587 = 31458654
113 + 31458541 = 31458654
127 + 31458527 = 31458654

Showing the first eight; more decompositions exist.
