Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474662, here are decompositions:

61 + 31474601 = 31474662
103 + 31474559 = 31474662
113 + 31474549 = 31474662
173 + 31474489 = 31474662
181 + 31474481 = 31474662
229 + 31474433 = 31474662
239 + 31474423 = 31474662
311 + 31474351 = 31474662

Showing the first eight; more decompositions exist.
