Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462126, here are decompositions:

23 + 31462103 = 31462126
149 + 31461977 = 31462126
233 + 31461893 = 31462126
239 + 31461887 = 31462126
347 + 31461779 = 31462126
383 + 31461743 = 31462126
389 + 31461737 = 31462126
557 + 31461569 = 31462126

Showing the first eight; more decompositions exist.
