Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473398, here are decompositions:

67 + 31473331 = 31473398
157 + 31473241 = 31473398
181 + 31473217 = 31473398
211 + 31473187 = 31473398
331 + 31473067 = 31473398
337 + 31473061 = 31473398
367 + 31473031 = 31473398
547 + 31472851 = 31473398

Showing the first eight; more decompositions exist.
