Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541066, here are decompositions:

19 + 31541047 = 31541066
127 + 31540939 = 31541066
199 + 31540867 = 31541066
229 + 31540837 = 31541066
283 + 31540783 = 31541066
367 + 31540699 = 31541066
373 + 31540693 = 31541066
397 + 31540669 = 31541066

Showing the first eight; more decompositions exist.
