Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483040, here are decompositions:

37 + 31483003 = 31483040
67 + 31482973 = 31483040
151 + 31482889 = 31483040
181 + 31482859 = 31483040
241 + 31482799 = 31483040
331 + 31482709 = 31483040
373 + 31482667 = 31483040
397 + 31482643 = 31483040

Showing the first eight; more decompositions exist.
