Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498230, here are decompositions:

13 + 31498217 = 31498230
17 + 31498213 = 31498230
31 + 31498199 = 31498230
37 + 31498193 = 31498230
41 + 31498189 = 31498230
79 + 31498151 = 31498230
107 + 31498123 = 31498230
191 + 31498039 = 31498230

Showing the first eight; more decompositions exist.
