Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462312, here are decompositions:

23 + 31462289 = 31462312
179 + 31462133 = 31462312
389 + 31461923 = 31462312
419 + 31461893 = 31462312
461 + 31461851 = 31462312
521 + 31461791 = 31462312
569 + 31461743 = 31462312
659 + 31461653 = 31462312

Showing the first eight; more decompositions exist.
