Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611032, here are decompositions:

3 + 31611029 = 31611032
139 + 31610893 = 31611032
241 + 31610791 = 31611032
463 + 31610569 = 31611032
619 + 31610413 = 31611032
643 + 31610389 = 31611032
919 + 31610113 = 31611032
1009 + 31610023 = 31611032

Showing the first eight; more decompositions exist.
