Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 471986, here are decompositions:

37 + 471949 = 471986
43 + 471943 = 471986
79 + 471907 = 471986
139 + 471847 = 471986
283 + 471703 = 471986
313 + 471673 = 471986
337 + 471649 = 471986
367 + 471619 = 471986

Showing the first eight; more decompositions exist.
