Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623176, here are decompositions:

3 + 31623173 = 31623176
7 + 31623169 = 31623176
229 + 31622947 = 31623176
283 + 31622893 = 31623176
313 + 31622863 = 31623176
367 + 31622809 = 31623176
373 + 31622803 = 31623176
397 + 31622779 = 31623176

Showing the first eight; more decompositions exist.
