Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474626, here are decompositions:

67 + 31474559 = 31474626
107 + 31474519 = 31474626
137 + 31474489 = 31474626
193 + 31474433 = 31474626
223 + 31474403 = 31474626
229 + 31474397 = 31474626
263 + 31474363 = 31474626
269 + 31474357 = 31474626

Showing the first eight; more decompositions exist.
