Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496154, here are decompositions:

13 + 31496141 = 31496154
31 + 31496123 = 31496154
71 + 31496083 = 31496154
97 + 31496057 = 31496154
113 + 31496041 = 31496154
127 + 31496027 = 31496154
233 + 31495921 = 31496154
257 + 31495897 = 31496154

Showing the first eight; more decompositions exist.
