Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31571606, here are decompositions:

37 + 31571569 = 31571606
109 + 31571497 = 31571606
139 + 31571467 = 31571606
193 + 31571413 = 31571606
223 + 31571383 = 31571606
349 + 31571257 = 31571606
439 + 31571167 = 31571606
457 + 31571149 = 31571606

Showing the first eight; more decompositions exist.
