Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523356, here are decompositions:

47 + 31523309 = 31523356
89 + 31523267 = 31523356
113 + 31523243 = 31523356
149 + 31523207 = 31523356
257 + 31523099 = 31523356
353 + 31523003 = 31523356
419 + 31522937 = 31523356
467 + 31522889 = 31523356

Showing the first eight; more decompositions exist.
