Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473698, here are decompositions:

211 + 31473487 = 31473698
241 + 31473457 = 31473698
367 + 31473331 = 31473698
457 + 31473241 = 31473698
547 + 31473151 = 31473698
631 + 31473067 = 31473698
661 + 31473037 = 31473698
769 + 31472929 = 31473698

Showing the first eight; more decompositions exist.
