Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610230, here are decompositions:

17 + 31610213 = 31610230
59 + 31610171 = 31610230
89 + 31610141 = 31610230
137 + 31610093 = 31610230
149 + 31610081 = 31610230
167 + 31610063 = 31610230
191 + 31610039 = 31610230
257 + 31609973 = 31610230

Showing the first eight; more decompositions exist.
