Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605010, here are decompositions:

23 + 31604987 = 31605010
251 + 31604759 = 31605010
263 + 31604747 = 31605010
383 + 31604627 = 31605010
401 + 31604609 = 31605010
449 + 31604561 = 31605010
509 + 31604501 = 31605010
557 + 31604453 = 31605010

Showing the first eight; more decompositions exist.
