Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567190, here are decompositions:

37 + 31567153 = 31567190
103 + 31567087 = 31567190
211 + 31566979 = 31567190
223 + 31566967 = 31567190
271 + 31566919 = 31567190
373 + 31566817 = 31567190
397 + 31566793 = 31567190
601 + 31566589 = 31567190

Showing the first eight; more decompositions exist.
