Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473914, here are decompositions:

7 + 31473907 = 31473914
13 + 31473901 = 31473914
67 + 31473847 = 31473914
103 + 31473811 = 31473914
181 + 31473733 = 31473914
211 + 31473703 = 31473914
331 + 31473583 = 31473914
457 + 31473457 = 31473914

Showing the first eight; more decompositions exist.
