Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567154, here are decompositions:

67 + 31567087 = 31567154
181 + 31566973 = 31567154
337 + 31566817 = 31567154
523 + 31566631 = 31567154
607 + 31566547 = 31567154
613 + 31566541 = 31567154
631 + 31566523 = 31567154
673 + 31566481 = 31567154

Showing the first eight; more decompositions exist.
