Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541108, here are decompositions:

7 + 31541101 = 31541108
37 + 31541071 = 31541108
61 + 31541047 = 31541108
241 + 31540867 = 31541108
271 + 31540837 = 31541108
409 + 31540699 = 31541108
439 + 31540669 = 31541108
457 + 31540651 = 31541108

Showing the first eight; more decompositions exist.
