Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567286, here are decompositions:

7 + 31567279 = 31567286
19 + 31567267 = 31567286
67 + 31567219 = 31567286
73 + 31567213 = 31567286
199 + 31567087 = 31567286
307 + 31566979 = 31567286
313 + 31566973 = 31567286
367 + 31566919 = 31567286

Showing the first eight; more decompositions exist.
