Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624250, here are decompositions:

103 + 31624147 = 31624250
109 + 31624141 = 31624250
181 + 31624069 = 31624250
271 + 31623979 = 31624250
283 + 31623967 = 31624250
349 + 31623901 = 31624250
433 + 31623817 = 31624250
547 + 31623703 = 31624250

Showing the first eight; more decompositions exist.
