Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624300, here are decompositions:

17 + 31624283 = 31624300
23 + 31624277 = 31624300
83 + 31624217 = 31624300
173 + 31624127 = 31624300
311 + 31623989 = 31624300
317 + 31623983 = 31624300
347 + 31623953 = 31624300
353 + 31623947 = 31624300

Showing the first eight; more decompositions exist.
