Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483904, here are decompositions:

43 + 31483861 = 31483904
97 + 31483807 = 31483904
103 + 31483801 = 31483904
181 + 31483723 = 31483904
241 + 31483663 = 31483904
307 + 31483597 = 31483904
433 + 31483471 = 31483904
457 + 31483447 = 31483904

Showing the first eight; more decompositions exist.
