Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481052, here are decompositions:

13 + 31481039 = 31481052
41 + 31481011 = 31481052
79 + 31480973 = 31481052
89 + 31480963 = 31481052
103 + 31480949 = 31481052
139 + 31480913 = 31481052
151 + 31480901 = 31481052
173 + 31480879 = 31481052

Showing the first eight; more decompositions exist.
