Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494654, here are decompositions:

11 + 31494643 = 31494654
17 + 31494637 = 31494654
43 + 31494611 = 31494654
71 + 31494583 = 31494654
73 + 31494581 = 31494654
101 + 31494553 = 31494654
151 + 31494503 = 31494654
157 + 31494497 = 31494654

Showing the first eight; more decompositions exist.
