Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477964, here are decompositions:

13 + 31477951 = 31477964
211 + 31477753 = 31477964
241 + 31477723 = 31477964
307 + 31477657 = 31477964
421 + 31477543 = 31477964
457 + 31477507 = 31477964
541 + 31477423 = 31477964
613 + 31477351 = 31477964

Showing the first eight; more decompositions exist.
