Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474648, here are decompositions:

47 + 31474601 = 31474648
71 + 31474577 = 31474648
89 + 31474559 = 31474648
167 + 31474481 = 31474648
251 + 31474397 = 31474648
347 + 31474301 = 31474648
431 + 31474217 = 31474648
587 + 31474061 = 31474648

Showing the first eight; more decompositions exist.
