Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497206, here are decompositions:

19 + 31497187 = 31497206
67 + 31497139 = 31497206
73 + 31497133 = 31497206
79 + 31497127 = 31497206
199 + 31497007 = 31497206
229 + 31496977 = 31497206
379 + 31496827 = 31497206
397 + 31496809 = 31497206

Showing the first eight; more decompositions exist.
