Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477708, here are decompositions:

11 + 31477697 = 31477708
131 + 31477577 = 31477708
137 + 31477571 = 31477708
281 + 31477427 = 31477708
359 + 31477349 = 31477708
419 + 31477289 = 31477708
641 + 31477067 = 31477708
761 + 31476947 = 31477708

Showing the first eight; more decompositions exist.
