Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476772, here are decompositions:

29 + 31476743 = 31476772
149 + 31476623 = 31476772
179 + 31476593 = 31476772
263 + 31476509 = 31476772
311 + 31476461 = 31476772
359 + 31476413 = 31476772
389 + 31476383 = 31476772
401 + 31476371 = 31476772

Showing the first eight; more decompositions exist.
