Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483158, here are decompositions:

41 + 31483117 = 31483158
61 + 31483097 = 31483158
71 + 31483087 = 31483158
89 + 31483069 = 31483158
97 + 31483061 = 31483158
107 + 31483051 = 31483158
167 + 31482991 = 31483158
181 + 31482977 = 31483158

Showing the first eight; more decompositions exist.
