Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474670, here are decompositions:

151 + 31474519 = 31474670
181 + 31474489 = 31474670
307 + 31474363 = 31474670
313 + 31474357 = 31474670
379 + 31474291 = 31474670
421 + 31474249 = 31474670
457 + 31474213 = 31474670
499 + 31474171 = 31474670

Showing the first eight; more decompositions exist.
