Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497108, here are decompositions:

37 + 31497071 = 31497108
101 + 31497007 = 31497108
107 + 31497001 = 31497108
131 + 31496977 = 31497108
151 + 31496957 = 31497108
191 + 31496917 = 31497108
281 + 31496827 = 31497108
317 + 31496791 = 31497108

Showing the first eight; more decompositions exist.
