Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481062, here are decompositions:

5 + 31481057 = 31481062
23 + 31481039 = 31481062
89 + 31480973 = 31481062
113 + 31480949 = 31481062
149 + 31480913 = 31481062
233 + 31480829 = 31481062
269 + 31480793 = 31481062
293 + 31480769 = 31481062

Showing the first eight; more decompositions exist.
