Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567076, here are decompositions:

97 + 31566979 = 31567076
103 + 31566973 = 31567076
109 + 31566967 = 31567076
157 + 31566919 = 31567076
283 + 31566793 = 31567076
313 + 31566763 = 31567076
367 + 31566709 = 31567076
487 + 31566589 = 31567076

Showing the first eight; more decompositions exist.
