Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523368, here are decompositions:

59 + 31523309 = 31523368
89 + 31523279 = 31523368
101 + 31523267 = 31523368
131 + 31523237 = 31523368
137 + 31523231 = 31523368
167 + 31523201 = 31523368
257 + 31523111 = 31523368
269 + 31523099 = 31523368

Showing the first eight; more decompositions exist.
