Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462252, here are decompositions:

149 + 31462103 = 31462252
359 + 31461893 = 31462252
401 + 31461851 = 31462252
461 + 31461791 = 31462252
491 + 31461761 = 31462252
509 + 31461743 = 31462252
599 + 31461653 = 31462252
683 + 31461569 = 31462252

Showing the first eight; more decompositions exist.
