Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458734, here are decompositions:

31 + 31458703 = 31458734
37 + 31458697 = 31458734
67 + 31458667 = 31458734
103 + 31458631 = 31458734
127 + 31458607 = 31458734
193 + 31458541 = 31458734
283 + 31458451 = 31458734
331 + 31458403 = 31458734

Showing the first eight; more decompositions exist.
