Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546508, here are decompositions:

139 + 31546369 = 31546508
157 + 31546351 = 31546508
229 + 31546279 = 31546508
241 + 31546267 = 31546508
277 + 31546231 = 31546508
349 + 31546159 = 31546508
379 + 31546129 = 31546508
397 + 31546111 = 31546508

Showing the first eight; more decompositions exist.
