Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610266, here are decompositions:

29 + 31610237 = 31610266
53 + 31610213 = 31610266
173 + 31610093 = 31610266
227 + 31610039 = 31610266
257 + 31610009 = 31610266
293 + 31609973 = 31610266
383 + 31609883 = 31610266
419 + 31609847 = 31610266

Showing the first eight; more decompositions exist.
