Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506546, here are decompositions:

17 + 31506529 = 31506546
23 + 31506523 = 31506546
67 + 31506479 = 31506546
103 + 31506443 = 31506546
109 + 31506437 = 31506546
173 + 31506373 = 31506546
179 + 31506367 = 31506546
193 + 31506353 = 31506546

Showing the first eight; more decompositions exist.
