Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462678, here are decompositions:

29 + 31462649 = 31462678
89 + 31462589 = 31462678
101 + 31462577 = 31462678
131 + 31462547 = 31462678
197 + 31462481 = 31462678
227 + 31462451 = 31462678
239 + 31462439 = 31462678
389 + 31462289 = 31462678

Showing the first eight; more decompositions exist.
