Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484726, here are decompositions:

79 + 31484647 = 31484726
109 + 31484617 = 31484726
157 + 31484569 = 31484726
193 + 31484533 = 31484726
223 + 31484503 = 31484726
277 + 31484449 = 31484726
313 + 31484413 = 31484726
349 + 31484377 = 31484726

Showing the first eight; more decompositions exist.
