Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534146, here are decompositions:

5 + 31534141 = 31534146
29 + 31534117 = 31534146
43 + 31534103 = 31534146
67 + 31534079 = 31534146
73 + 31534073 = 31534146
79 + 31534067 = 31534146
89 + 31534057 = 31534146
113 + 31534033 = 31534146

Showing the first eight; more decompositions exist.
