Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567082, here are decompositions:

103 + 31566979 = 31567082
109 + 31566973 = 31567082
163 + 31566919 = 31567082
181 + 31566901 = 31567082
373 + 31566709 = 31567082
523 + 31566559 = 31567082
541 + 31566541 = 31567082
601 + 31566481 = 31567082

Showing the first eight; more decompositions exist.
