Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541576, here are decompositions:

7 + 31541569 = 31541576
13 + 31541563 = 31541576
19 + 31541557 = 31541576
67 + 31541509 = 31541576
109 + 31541467 = 31541576
127 + 31541449 = 31541576
139 + 31541437 = 31541576
229 + 31541347 = 31541576

Showing the first eight; more decompositions exist.
