Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623296, here are decompositions:

73 + 31623223 = 31623296
97 + 31623199 = 31623296
127 + 31623169 = 31623296
337 + 31622959 = 31623296
349 + 31622947 = 31623296
373 + 31622923 = 31623296
433 + 31622863 = 31623296
487 + 31622809 = 31623296

Showing the first eight; more decompositions exist.
