Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538348, here are decompositions:

19 + 31538329 = 31538348
97 + 31538251 = 31538348
109 + 31538239 = 31538348
211 + 31538137 = 31538348
241 + 31538107 = 31538348
277 + 31538071 = 31538348
349 + 31537999 = 31538348
367 + 31537981 = 31538348

Showing the first eight; more decompositions exist.
