Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477946, here are decompositions:

67 + 31477879 = 31477946
193 + 31477753 = 31477946
223 + 31477723 = 31477946
229 + 31477717 = 31477946
277 + 31477669 = 31477946
397 + 31477549 = 31477946
433 + 31477513 = 31477946
439 + 31477507 = 31477946

Showing the first eight; more decompositions exist.
