Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567370, here are decompositions:

73 + 31567297 = 31567370
103 + 31567267 = 31567370
139 + 31567231 = 31567370
151 + 31567219 = 31567370
157 + 31567213 = 31567370
283 + 31567087 = 31567370
397 + 31566973 = 31567370
577 + 31566793 = 31567370

Showing the first eight; more decompositions exist.
