Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623260, here are decompositions:

3 + 31623257 = 31623260
37 + 31623223 = 31623260
61 + 31623199 = 31623260
79 + 31623181 = 31623260
139 + 31623121 = 31623260
199 + 31623061 = 31623260
313 + 31622947 = 31623260
337 + 31622923 = 31623260

Showing the first eight; more decompositions exist.
