Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447410, here are decompositions:

17 + 31447393 = 31447410
31 + 31447379 = 31447410
47 + 31447363 = 31447410
53 + 31447357 = 31447410
109 + 31447301 = 31447410
157 + 31447253 = 31447410
193 + 31447217 = 31447410
199 + 31447211 = 31447410

Showing the first eight; more decompositions exist.
