Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610098, here are decompositions:

5 + 31610093 = 31610098
17 + 31610081 = 31610098
59 + 31610039 = 31610098
89 + 31610009 = 31610098
131 + 31609967 = 31610098
167 + 31609931 = 31610098
227 + 31609871 = 31610098
251 + 31609847 = 31610098

Showing the first eight; more decompositions exist.
