Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462042, here are decompositions:

149 + 31461893 = 31462042
191 + 31461851 = 31462042
251 + 31461791 = 31462042
263 + 31461779 = 31462042
281 + 31461761 = 31462042
389 + 31461653 = 31462042
401 + 31461641 = 31462042
509 + 31461533 = 31462042

Showing the first eight; more decompositions exist.
