Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623302, here are decompositions:

79 + 31623223 = 31623302
103 + 31623199 = 31623302
181 + 31623121 = 31623302
241 + 31623061 = 31623302
379 + 31622923 = 31623302
409 + 31622893 = 31623302
421 + 31622881 = 31623302
439 + 31622863 = 31623302

Showing the first eight; more decompositions exist.
