Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610898, here are decompositions:

5 + 31610893 = 31610898
31 + 31610867 = 31610898
107 + 31610791 = 31610898
127 + 31610771 = 31610898
157 + 31610741 = 31610898
191 + 31610707 = 31610898
257 + 31610641 = 31610898
269 + 31610629 = 31610898

Showing the first eight; more decompositions exist.
