Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474628, here are decompositions:

79 + 31474549 = 31474628
109 + 31474519 = 31474628
127 + 31474501 = 31474628
139 + 31474489 = 31474628
271 + 31474357 = 31474628
277 + 31474351 = 31474628
337 + 31474291 = 31474628
379 + 31474249 = 31474628

Showing the first eight; more decompositions exist.
