Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461182, here are decompositions:

3 + 31461179 = 31461182
19 + 31461163 = 31461182
211 + 31460971 = 31461182
331 + 31460851 = 31461182
349 + 31460833 = 31461182
373 + 31460809 = 31461182
439 + 31460743 = 31461182
601 + 31460581 = 31461182

Showing the first eight; more decompositions exist.
