Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462828, here are decompositions:

17 + 31462811 = 31462828
71 + 31462757 = 31462828
179 + 31462649 = 31462828
239 + 31462589 = 31462828
251 + 31462577 = 31462828
281 + 31462547 = 31462828
347 + 31462481 = 31462828
389 + 31462439 = 31462828

Showing the first eight; more decompositions exist.
