Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498832, here are decompositions:

3 + 31498829 = 31498832
19 + 31498813 = 31498832
193 + 31498639 = 31498832
241 + 31498591 = 31498832
283 + 31498549 = 31498832
619 + 31498213 = 31498832
643 + 31498189 = 31498832
709 + 31498123 = 31498832

Showing the first eight; more decompositions exist.
