Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610488, here are decompositions:

149 + 31610339 = 31610488
197 + 31610291 = 31610488
251 + 31610237 = 31610488
257 + 31610231 = 31610488
317 + 31610171 = 31610488
347 + 31610141 = 31610488
449 + 31610039 = 31610488
479 + 31610009 = 31610488

Showing the first eight; more decompositions exist.
