Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624092, here are decompositions:

23 + 31624069 = 31624092
79 + 31624013 = 31624092
89 + 31624003 = 31624092
103 + 31623989 = 31624092
109 + 31623983 = 31624092
113 + 31623979 = 31624092
139 + 31623953 = 31624092
163 + 31623929 = 31624092

Showing the first eight; more decompositions exist.
