Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567340, here are decompositions:

43 + 31567297 = 31567340
61 + 31567279 = 31567340
73 + 31567267 = 31567340
109 + 31567231 = 31567340
127 + 31567213 = 31567340
367 + 31566973 = 31567340
373 + 31566967 = 31567340
421 + 31566919 = 31567340

Showing the first eight; more decompositions exist.
