Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472410, here are decompositions:

59 + 31472351 = 31472410
71 + 31472339 = 31472410
149 + 31472261 = 31472410
227 + 31472183 = 31472410
251 + 31472159 = 31472410
257 + 31472153 = 31472410
419 + 31471991 = 31472410
443 + 31471967 = 31472410

Showing the first eight; more decompositions exist.
