Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552686, here are decompositions:

5 + 31552681 = 31552686
43 + 31552643 = 31552686
47 + 31552639 = 31552686
83 + 31552603 = 31552686
97 + 31552589 = 31552686
107 + 31552579 = 31552686
149 + 31552537 = 31552686
197 + 31552489 = 31552686

Showing the first eight; more decompositions exist.
