Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523854, here are decompositions:

3 + 31523851 = 31523854
53 + 31523801 = 31523854
101 + 31523753 = 31523854
317 + 31523537 = 31523854
443 + 31523411 = 31523854
587 + 31523267 = 31523854
617 + 31523237 = 31523854
647 + 31523207 = 31523854

Showing the first eight; more decompositions exist.
