Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623326, here are decompositions:

103 + 31623223 = 31623326
127 + 31623199 = 31623326
157 + 31623169 = 31623326
367 + 31622959 = 31623326
379 + 31622947 = 31623326
433 + 31622893 = 31623326
463 + 31622863 = 31623326
523 + 31622803 = 31623326

Showing the first eight; more decompositions exist.
