Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523348, here are decompositions:

19 + 31523329 = 31523348
97 + 31523251 = 31523348
127 + 31523221 = 31523348
139 + 31523209 = 31523348
229 + 31523119 = 31523348
397 + 31522951 = 31523348
601 + 31522747 = 31523348
631 + 31522717 = 31523348

Showing the first eight; more decompositions exist.
