Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460432, here are decompositions:

19 + 31460413 = 31460432
103 + 31460329 = 31460432
139 + 31460293 = 31460432
151 + 31460281 = 31460432
379 + 31460053 = 31460432
433 + 31459999 = 31460432
439 + 31459993 = 31460432
541 + 31459891 = 31460432

Showing the first eight; more decompositions exist.
