Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477616, here are decompositions:

13 + 31477603 = 31477616
67 + 31477549 = 31477616
73 + 31477543 = 31477616
103 + 31477513 = 31477616
109 + 31477507 = 31477616
193 + 31477423 = 31477616
409 + 31477207 = 31477616
769 + 31476847 = 31477616

Showing the first eight; more decompositions exist.
