Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624194, here are decompositions:

47 + 31624147 = 31624194
53 + 31624141 = 31624194
67 + 31624127 = 31624194
181 + 31624013 = 31624194
191 + 31624003 = 31624194
193 + 31624001 = 31624194
211 + 31623983 = 31624194
223 + 31623971 = 31624194

Showing the first eight; more decompositions exist.
