Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474038, here are decompositions:

5 + 31474033 = 31474038
31 + 31474007 = 31474038
47 + 31473991 = 31474038
61 + 31473977 = 31474038
67 + 31473971 = 31474038
107 + 31473931 = 31474038
131 + 31473907 = 31474038
137 + 31473901 = 31474038

Showing the first eight; more decompositions exist.
