Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568654, here are decompositions:

43 + 31568611 = 31568654
67 + 31568587 = 31568654
127 + 31568527 = 31568654
157 + 31568497 = 31568654
163 + 31568491 = 31568654
241 + 31568413 = 31568654
307 + 31568347 = 31568654
367 + 31568287 = 31568654

Showing the first eight; more decompositions exist.
