Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623476, here are decompositions:

37 + 31623439 = 31623476
103 + 31623373 = 31623476
139 + 31623337 = 31623476
277 + 31623199 = 31623476
307 + 31623169 = 31623476
613 + 31622863 = 31623476
673 + 31622803 = 31623476
733 + 31622743 = 31623476

Showing the first eight; more decompositions exist.
