Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541592, here are decompositions:

11 + 31541581 = 31541592
23 + 31541569 = 31541592
29 + 31541563 = 31541592
83 + 31541509 = 31541592
109 + 31541483 = 31541592
163 + 31541429 = 31541592
191 + 31541401 = 31541592
193 + 31541399 = 31541592

Showing the first eight; more decompositions exist.
