Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474520, here are decompositions:

19 + 31474501 = 31474520
31 + 31474489 = 31474520
97 + 31474423 = 31474520
157 + 31474363 = 31474520
163 + 31474357 = 31474520
229 + 31474291 = 31474520
271 + 31474249 = 31474520
307 + 31474213 = 31474520

Showing the first eight; more decompositions exist.
