Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609834, here are decompositions:

41 + 31609793 = 31609834
131 + 31609703 = 31609834
173 + 31609661 = 31609834
251 + 31609583 = 31609834
257 + 31609577 = 31609834
293 + 31609541 = 31609834
353 + 31609481 = 31609834
383 + 31609451 = 31609834

Showing the first eight; more decompositions exist.
