Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462834, here are decompositions:

3 + 31462831 = 31462834
23 + 31462811 = 31462834
41 + 31462793 = 31462834
83 + 31462751 = 31462834
251 + 31462583 = 31462834
257 + 31462577 = 31462834
281 + 31462553 = 31462834
353 + 31462481 = 31462834

Showing the first eight; more decompositions exist.
