Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474342, here are decompositions:

23 + 31474319 = 31474342
41 + 31474301 = 31474342
89 + 31474253 = 31474342
269 + 31474073 = 31474342
281 + 31474061 = 31474342
479 + 31473863 = 31474342
503 + 31473839 = 31474342
563 + 31473779 = 31474342

Showing the first eight; more decompositions exist.
