Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474492, here are decompositions:

3 + 31474489 = 31474492
11 + 31474481 = 31474492
59 + 31474433 = 31474492
89 + 31474403 = 31474492
149 + 31474343 = 31474492
173 + 31474319 = 31474492
191 + 31474301 = 31474492
239 + 31474253 = 31474492

Showing the first eight; more decompositions exist.
