Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609450, here are decompositions:

227 + 31609223 = 31609450
359 + 31609091 = 31609450
401 + 31609049 = 31609450
419 + 31609031 = 31609450
479 + 31608971 = 31609450
491 + 31608959 = 31609450
557 + 31608893 = 31609450
563 + 31608887 = 31609450

Showing the first eight; more decompositions exist.
