Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460788, here are decompositions:

5 + 31460783 = 31460788
59 + 31460729 = 31460788
71 + 31460717 = 31460788
131 + 31460657 = 31460788
179 + 31460609 = 31460788
239 + 31460549 = 31460788
251 + 31460537 = 31460788
347 + 31460441 = 31460788

Showing the first eight; more decompositions exist.
