Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474104, here are decompositions:

31 + 31474073 = 31474104
43 + 31474061 = 31474104
47 + 31474057 = 31474104
61 + 31474043 = 31474104
71 + 31474033 = 31474104
97 + 31474007 = 31474104
113 + 31473991 = 31474104
127 + 31473977 = 31474104

Showing the first eight; more decompositions exist.
