Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476532, here are decompositions:

23 + 31476509 = 31476532
71 + 31476461 = 31476532
83 + 31476449 = 31476532
149 + 31476383 = 31476532
179 + 31476353 = 31476532
281 + 31476251 = 31476532
293 + 31476239 = 31476532
383 + 31476149 = 31476532

Showing the first eight; more decompositions exist.
