Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481076, here are decompositions:

19 + 31481057 = 31481076
37 + 31481039 = 31481076
103 + 31480973 = 31481076
113 + 31480963 = 31481076
127 + 31480949 = 31481076
157 + 31480919 = 31481076
163 + 31480913 = 31481076
197 + 31480879 = 31481076

Showing the first eight; more decompositions exist.
