Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474146, here are decompositions:

5 + 31474141 = 31474146
17 + 31474129 = 31474146
73 + 31474073 = 31474146
89 + 31474057 = 31474146
103 + 31474043 = 31474146
113 + 31474033 = 31474146
139 + 31474007 = 31474146
229 + 31473917 = 31474146

Showing the first eight; more decompositions exist.
