Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567400, here are decompositions:

3 + 31567397 = 31567400
31 + 31567369 = 31567400
103 + 31567297 = 31567400
181 + 31567219 = 31567400
313 + 31567087 = 31567400
421 + 31566979 = 31567400
433 + 31566967 = 31567400
499 + 31566901 = 31567400

Showing the first eight; more decompositions exist.
