Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497066, here are decompositions:

59 + 31497007 = 31497066
89 + 31496977 = 31497066
103 + 31496963 = 31497066
109 + 31496957 = 31497066
149 + 31496917 = 31497066
193 + 31496873 = 31497066
239 + 31496827 = 31497066
257 + 31496809 = 31497066

Showing the first eight; more decompositions exist.
