Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523546, here are decompositions:

7 + 31523539 = 31523546
73 + 31523473 = 31523546
79 + 31523467 = 31523546
127 + 31523419 = 31523546
139 + 31523407 = 31523546
199 + 31523347 = 31523546
337 + 31523209 = 31523546
433 + 31523113 = 31523546

Showing the first eight; more decompositions exist.
