Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31226, here are decompositions:

3 + 31223 = 31226
7 + 31219 = 31226
37 + 31189 = 31226
43 + 31183 = 31226
67 + 31159 = 31226
73 + 31153 = 31226
79 + 31147 = 31226
103 + 31123 = 31226

Showing the first eight; more decompositions exist.
