Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567182, here are decompositions:

29 + 31567153 = 31567182
139 + 31567043 = 31567182
263 + 31566919 = 31567182
271 + 31566911 = 31567182
281 + 31566901 = 31567182
379 + 31566803 = 31567182
389 + 31566793 = 31567182
419 + 31566763 = 31567182

Showing the first eight; more decompositions exist.
