Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624058, here are decompositions:

79 + 31623979 = 31624058
127 + 31623931 = 31624058
157 + 31623901 = 31624058
241 + 31623817 = 31624058
337 + 31623721 = 31624058
547 + 31623511 = 31624058
577 + 31623481 = 31624058
619 + 31623439 = 31624058

Showing the first eight; more decompositions exist.
