Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567192, here are decompositions:

101 + 31567091 = 31567192
149 + 31567043 = 31567192
281 + 31566911 = 31567192
353 + 31566839 = 31567192
389 + 31566803 = 31567192
443 + 31566749 = 31567192
479 + 31566713 = 31567192
593 + 31566599 = 31567192

Showing the first eight; more decompositions exist.
