Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537876, here are decompositions:

5 + 31537871 = 31537876
17 + 31537859 = 31537876
53 + 31537823 = 31537876
317 + 31537559 = 31537876
443 + 31537433 = 31537876
467 + 31537409 = 31537876
563 + 31537313 = 31537876
569 + 31537307 = 31537876

Showing the first eight; more decompositions exist.
