Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541468, here are decompositions:

19 + 31541449 = 31541468
31 + 31541437 = 31541468
67 + 31541401 = 31541468
109 + 31541359 = 31541468
199 + 31541269 = 31541468
307 + 31541161 = 31541468
367 + 31541101 = 31541468
397 + 31541071 = 31541468

Showing the first eight; more decompositions exist.
