Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620248, here are decompositions:

19 + 31620229 = 31620248
97 + 31620151 = 31620248
109 + 31620139 = 31620248
139 + 31620109 = 31620248
181 + 31620067 = 31620248
211 + 31620037 = 31620248
229 + 31620019 = 31620248
337 + 31619911 = 31620248

Showing the first eight; more decompositions exist.
