Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477006, here are decompositions:

47 + 31476959 = 31477006
59 + 31476947 = 31477006
89 + 31476917 = 31477006
263 + 31476743 = 31477006
383 + 31476623 = 31477006
419 + 31476587 = 31477006
557 + 31476449 = 31477006
569 + 31476437 = 31477006

Showing the first eight; more decompositions exist.
