Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567070, here are decompositions:

97 + 31566973 = 31567070
103 + 31566967 = 31567070
151 + 31566919 = 31567070
277 + 31566793 = 31567070
307 + 31566763 = 31567070
439 + 31566631 = 31567070
523 + 31566547 = 31567070
547 + 31566523 = 31567070

Showing the first eight; more decompositions exist.
