Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611098, here are decompositions:

31 + 31611067 = 31611098
61 + 31611037 = 31611098
307 + 31610791 = 31611098
457 + 31610641 = 31611098
577 + 31610521 = 31611098
661 + 31610437 = 31611098
709 + 31610389 = 31611098
811 + 31610287 = 31611098

Showing the first eight; more decompositions exist.
