Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497654, here are decompositions:

17 + 31497637 = 31497654
53 + 31497601 = 31497654
103 + 31497551 = 31497654
107 + 31497547 = 31497654
113 + 31497541 = 31497654
127 + 31497527 = 31497654
131 + 31497523 = 31497654
163 + 31497491 = 31497654

Showing the first eight; more decompositions exist.
