Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624098, here are decompositions:

29 + 31624069 = 31624098
97 + 31624001 = 31624098
109 + 31623989 = 31624098
127 + 31623971 = 31624098
131 + 31623967 = 31624098
139 + 31623959 = 31624098
151 + 31623947 = 31624098
167 + 31623931 = 31624098

Showing the first eight; more decompositions exist.
