Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523468, here are decompositions:

7 + 31523461 = 31523468
61 + 31523407 = 31523468
139 + 31523329 = 31523468
241 + 31523227 = 31523468
307 + 31523161 = 31523468
337 + 31523131 = 31523468
349 + 31523119 = 31523468
751 + 31522717 = 31523468

Showing the first eight; more decompositions exist.
