Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567694, here are decompositions:

7 + 31567687 = 31567694
13 + 31567681 = 31567694
73 + 31567621 = 31567694
181 + 31567513 = 31567694
283 + 31567411 = 31567694
397 + 31567297 = 31567694
463 + 31567231 = 31567694
541 + 31567153 = 31567694

Showing the first eight; more decompositions exist.
