Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567346, here are decompositions:

67 + 31567279 = 31567346
79 + 31567267 = 31567346
127 + 31567219 = 31567346
193 + 31567153 = 31567346
367 + 31566979 = 31567346
373 + 31566973 = 31567346
379 + 31566967 = 31567346
757 + 31566589 = 31567346

Showing the first eight; more decompositions exist.
