Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477862, here are decompositions:

103 + 31477759 = 31477862
109 + 31477753 = 31477862
139 + 31477723 = 31477862
151 + 31477711 = 31477862
193 + 31477669 = 31477862
313 + 31477549 = 31477862
349 + 31477513 = 31477862
379 + 31477483 = 31477862

Showing the first eight; more decompositions exist.
