Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472510, here are decompositions:

31 + 31472479 = 31472510
61 + 31472449 = 31472510
73 + 31472437 = 31472510
151 + 31472359 = 31472510
271 + 31472239 = 31472510
331 + 31472179 = 31472510
367 + 31472143 = 31472510
379 + 31472131 = 31472510

Showing the first eight; more decompositions exist.
