Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496474, here are decompositions:

103 + 31496371 = 31496474
157 + 31496317 = 31496474
181 + 31496293 = 31496474
211 + 31496263 = 31496474
313 + 31496161 = 31496474
433 + 31496041 = 31496474
463 + 31496011 = 31496474
577 + 31495897 = 31496474

Showing the first eight; more decompositions exist.
