Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479662, here are decompositions:

13 + 31479649 = 31479662
43 + 31479619 = 31479662
73 + 31479589 = 31479662
103 + 31479559 = 31479662
163 + 31479499 = 31479662
223 + 31479439 = 31479662
241 + 31479421 = 31479662
373 + 31479289 = 31479662

Showing the first eight; more decompositions exist.
