Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473974, here are decompositions:

3 + 31473971 = 31473974
43 + 31473931 = 31473974
67 + 31473907 = 31473974
73 + 31473901 = 31473974
127 + 31473847 = 31473974
163 + 31473811 = 31473974
193 + 31473781 = 31473974
241 + 31473733 = 31473974

Showing the first eight; more decompositions exist.
