Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496318, here are decompositions:

97 + 31496221 = 31496318
109 + 31496209 = 31496318
157 + 31496161 = 31496318
199 + 31496119 = 31496318
277 + 31496041 = 31496318
307 + 31496011 = 31496318
397 + 31495921 = 31496318
421 + 31495897 = 31496318

Showing the first eight; more decompositions exist.
