Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612248, here are decompositions:

7 + 31612241 = 31612248
47 + 31612201 = 31612248
97 + 31612151 = 31612248
127 + 31612121 = 31612248
139 + 31612109 = 31612248
167 + 31612081 = 31612248
179 + 31612069 = 31612248
251 + 31611997 = 31612248

Showing the first eight; more decompositions exist.
