Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473498, here are decompositions:

11 + 31473487 = 31473498
19 + 31473479 = 31473498
41 + 31473457 = 31473498
61 + 31473437 = 31473498
101 + 31473397 = 31473498
139 + 31473359 = 31473498
167 + 31473331 = 31473498
257 + 31473241 = 31473498

Showing the first eight; more decompositions exist.
