Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623200, here are decompositions:

19 + 31623181 = 31623200
31 + 31623169 = 31623200
79 + 31623121 = 31623200
139 + 31623061 = 31623200
241 + 31622959 = 31623200
277 + 31622923 = 31623200
307 + 31622893 = 31623200
337 + 31622863 = 31623200

Showing the first eight; more decompositions exist.
