Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484102, here are decompositions:

31 + 31484071 = 31484102
43 + 31484059 = 31484102
241 + 31483861 = 31484102
283 + 31483819 = 31484102
313 + 31483789 = 31484102
379 + 31483723 = 31484102
439 + 31483663 = 31484102
631 + 31483471 = 31484102

Showing the first eight; more decompositions exist.
