Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531076, here are decompositions:

7 + 31531069 = 31531076
13 + 31531063 = 31531076
19 + 31531057 = 31531076
97 + 31530979 = 31531076
103 + 31530973 = 31531076
277 + 31530799 = 31531076
373 + 31530703 = 31531076
397 + 31530679 = 31531076

Showing the first eight; more decompositions exist.
