Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506794, here are decompositions:

3 + 31506791 = 31506794
13 + 31506781 = 31506794
97 + 31506697 = 31506794
271 + 31506523 = 31506794
283 + 31506511 = 31506794
373 + 31506421 = 31506794
421 + 31506373 = 31506794
463 + 31506331 = 31506794

Showing the first eight; more decompositions exist.
