Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624292, here are decompositions:

151 + 31624141 = 31624292
163 + 31624129 = 31624292
223 + 31624069 = 31624292
313 + 31623979 = 31624292
571 + 31623721 = 31624292
769 + 31623523 = 31624292
811 + 31623481 = 31624292
853 + 31623439 = 31624292

Showing the first eight; more decompositions exist.
