Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532476, here are decompositions:

47 + 31532429 = 31532476
137 + 31532339 = 31532476
197 + 31532279 = 31532476
257 + 31532219 = 31532476
359 + 31532117 = 31532476
509 + 31531967 = 31532476
593 + 31531883 = 31532476
659 + 31531817 = 31532476

Showing the first eight; more decompositions exist.
