Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606016, here are decompositions:

103 + 31605913 = 31606016
139 + 31605877 = 31606016
193 + 31605823 = 31606016
397 + 31605619 = 31606016
433 + 31605583 = 31606016
439 + 31605577 = 31606016
499 + 31605517 = 31606016
577 + 31605439 = 31606016

Showing the first eight; more decompositions exist.
