Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474718, here are decompositions:

31 + 31474687 = 31474718
199 + 31474519 = 31474718
229 + 31474489 = 31474718
367 + 31474351 = 31474718
547 + 31474171 = 31474718
577 + 31474141 = 31474718
607 + 31474111 = 31474718
661 + 31474057 = 31474718

Showing the first eight; more decompositions exist.
