Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483898, here are decompositions:

37 + 31483861 = 31483898
79 + 31483819 = 31483898
97 + 31483801 = 31483898
109 + 31483789 = 31483898
139 + 31483759 = 31483898
349 + 31483549 = 31483898
547 + 31483351 = 31483898
571 + 31483327 = 31483898

Showing the first eight; more decompositions exist.
