Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472450, here are decompositions:

13 + 31472437 = 31472450
157 + 31472293 = 31472450
211 + 31472239 = 31472450
241 + 31472209 = 31472450
271 + 31472179 = 31472450
283 + 31472167 = 31472450
307 + 31472143 = 31472450
397 + 31472053 = 31472450

Showing the first eight; more decompositions exist.
