Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474426, here are decompositions:

3 + 31474423 = 31474426
23 + 31474403 = 31474426
29 + 31474397 = 31474426
83 + 31474343 = 31474426
107 + 31474319 = 31474426
173 + 31474253 = 31474426
353 + 31474073 = 31474426
383 + 31474043 = 31474426

Showing the first eight; more decompositions exist.
