Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567140, here are decompositions:

53 + 31567087 = 31567140
97 + 31567043 = 31567140
167 + 31566973 = 31567140
173 + 31566967 = 31567140
229 + 31566911 = 31567140
239 + 31566901 = 31567140
277 + 31566863 = 31567140
313 + 31566827 = 31567140

Showing the first eight; more decompositions exist.
