Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599678, here are decompositions:

7 + 31599671 = 31599678
29 + 31599649 = 31599678
67 + 31599611 = 31599678
79 + 31599599 = 31599678
127 + 31599551 = 31599678
179 + 31599499 = 31599678
191 + 31599487 = 31599678
239 + 31599439 = 31599678

Showing the first eight; more decompositions exist.
