Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496498, here are decompositions:

79 + 31496419 = 31496498
109 + 31496389 = 31496498
127 + 31496371 = 31496498
181 + 31496317 = 31496498
277 + 31496221 = 31496498
337 + 31496161 = 31496498
379 + 31496119 = 31496498
457 + 31496041 = 31496498

Showing the first eight; more decompositions exist.
