Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476680, here are decompositions:

73 + 31476607 = 31476680
163 + 31476517 = 31476680
181 + 31476499 = 31476680
223 + 31476457 = 31476680
229 + 31476451 = 31476680
307 + 31476373 = 31476680
331 + 31476349 = 31476680
337 + 31476343 = 31476680

Showing the first eight; more decompositions exist.
