Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483844, here are decompositions:

3 + 31483841 = 31483844
37 + 31483807 = 31483844
43 + 31483801 = 31483844
181 + 31483663 = 31483844
373 + 31483471 = 31483844
397 + 31483447 = 31483844
607 + 31483237 = 31483844
631 + 31483213 = 31483844

Showing the first eight; more decompositions exist.
