Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559182, here are decompositions:

89 + 31559093 = 31559182
101 + 31559081 = 31559182
113 + 31559069 = 31559182
131 + 31559051 = 31559182
359 + 31558823 = 31559182
383 + 31558799 = 31559182
449 + 31558733 = 31559182
509 + 31558673 = 31559182

Showing the first eight; more decompositions exist.
