Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473404, here are decompositions:

7 + 31473397 = 31473404
73 + 31473331 = 31473404
163 + 31473241 = 31473404
241 + 31473163 = 31473404
337 + 31473067 = 31473404
367 + 31473037 = 31473404
373 + 31473031 = 31473404
421 + 31472983 = 31473404

Showing the first eight; more decompositions exist.
