Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476388, here are decompositions:

5 + 31476383 = 31476388
17 + 31476371 = 31476388
71 + 31476317 = 31476388
137 + 31476251 = 31476388
149 + 31476239 = 31476388
239 + 31476149 = 31476388
269 + 31476119 = 31476388
479 + 31475909 = 31476388

Showing the first eight; more decompositions exist.
