Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31580534, here are decompositions:

3 + 31580531 = 31580534
31 + 31580503 = 31580534
211 + 31580323 = 31580534
241 + 31580293 = 31580534
277 + 31580257 = 31580534
313 + 31580221 = 31580534
421 + 31580113 = 31580534
457 + 31580077 = 31580534

Showing the first eight; more decompositions exist.
