Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476372, here are decompositions:

19 + 31476353 = 31476372
23 + 31476349 = 31476372
29 + 31476343 = 31476372
89 + 31476283 = 31476372
223 + 31476149 = 31476372
229 + 31476143 = 31476372
313 + 31476059 = 31476372
359 + 31476013 = 31476372

Showing the first eight; more decompositions exist.
