Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474044, here are decompositions:

11 + 31474033 = 31474044
37 + 31474007 = 31474044
53 + 31473991 = 31474044
67 + 31473977 = 31474044
73 + 31473971 = 31474044
113 + 31473931 = 31474044
127 + 31473917 = 31474044
137 + 31473907 = 31474044

Showing the first eight; more decompositions exist.
