Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610170, here are decompositions:

29 + 31610141 = 31610170
89 + 31610081 = 31610170
107 + 31610063 = 31610170
131 + 31610039 = 31610170
197 + 31609973 = 31610170
233 + 31609937 = 31610170
239 + 31609931 = 31610170
401 + 31609769 = 31610170

Showing the first eight; more decompositions exist.
