Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462102, here are decompositions:

179 + 31461923 = 31462102
251 + 31461851 = 31462102
311 + 31461791 = 31462102
359 + 31461743 = 31462102
449 + 31461653 = 31462102
461 + 31461641 = 31462102
569 + 31461533 = 31462102
761 + 31461341 = 31462102

Showing the first eight; more decompositions exist.
