Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567112, here are decompositions:

139 + 31566973 = 31567112
193 + 31566919 = 31567112
211 + 31566901 = 31567112
349 + 31566763 = 31567112
523 + 31566589 = 31567112
571 + 31566541 = 31567112
631 + 31566481 = 31567112
823 + 31566289 = 31567112

Showing the first eight; more decompositions exist.
