Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483206, here are decompositions:

37 + 31483169 = 31483206
43 + 31483163 = 31483206
89 + 31483117 = 31483206
109 + 31483097 = 31483206
113 + 31483093 = 31483206
137 + 31483069 = 31483206
229 + 31482977 = 31483206
233 + 31482973 = 31483206

Showing the first eight; more decompositions exist.
