Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476340, here are decompositions:

23 + 31476317 = 31476340
89 + 31476251 = 31476340
101 + 31476239 = 31476340
191 + 31476149 = 31476340
197 + 31476143 = 31476340
227 + 31476113 = 31476340
281 + 31476059 = 31476340
431 + 31475909 = 31476340

Showing the first eight; more decompositions exist.
