Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528974, here are decompositions:

5 + 31528969 = 31528974
7 + 31528967 = 31528974
131 + 31528843 = 31528974
151 + 31528823 = 31528974
163 + 31528811 = 31528974
167 + 31528807 = 31528974
173 + 31528801 = 31528974
223 + 31528751 = 31528974

Showing the first eight; more decompositions exist.
