Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526292, here are decompositions:

11 + 31526281 = 31526292
19 + 31526273 = 31526292
53 + 31526239 = 31526292
71 + 31526221 = 31526292
79 + 31526213 = 31526292
101 + 31526191 = 31526292
103 + 31526189 = 31526292
151 + 31526141 = 31526292

Showing the first eight; more decompositions exist.
