Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541802, here are decompositions:

41 + 31541761 = 31541802
109 + 31541693 = 31541802
151 + 31541651 = 31541802
191 + 31541611 = 31541802
211 + 31541591 = 31541802
233 + 31541569 = 31541802
239 + 31541563 = 31541802
293 + 31541509 = 31541802

Showing the first eight; more decompositions exist.
