Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31580606, here are decompositions:

67 + 31580539 = 31580606
103 + 31580503 = 31580606
283 + 31580323 = 31580606
313 + 31580293 = 31580606
349 + 31580257 = 31580606
367 + 31580239 = 31580606
373 + 31580233 = 31580606
457 + 31580149 = 31580606

Showing the first eight; more decompositions exist.
