Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468866, here are decompositions:

5 + 31468861 = 31468866
17 + 31468849 = 31468866
43 + 31468823 = 31468866
73 + 31468793 = 31468866
89 + 31468777 = 31468866
109 + 31468757 = 31468866
139 + 31468727 = 31468866
167 + 31468699 = 31468866

Showing the first eight; more decompositions exist.
