Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624268, here are decompositions:

127 + 31624141 = 31624268
139 + 31624129 = 31624268
199 + 31624069 = 31624268
337 + 31623931 = 31624268
367 + 31623901 = 31624268
547 + 31623721 = 31624268
601 + 31623667 = 31624268
661 + 31623607 = 31624268

Showing the first eight; more decompositions exist.
