Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567120, here are decompositions:

29 + 31567091 = 31567120
71 + 31567049 = 31567120
257 + 31566863 = 31567120
281 + 31566839 = 31567120
293 + 31566827 = 31567120
317 + 31566803 = 31567120
383 + 31566737 = 31567120
461 + 31566659 = 31567120

Showing the first eight; more decompositions exist.
