Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541876, here are decompositions:

7 + 31541869 = 31541876
19 + 31541857 = 31541876
139 + 31541737 = 31541876
199 + 31541677 = 31541876
307 + 31541569 = 31541876
313 + 31541563 = 31541876
349 + 31541527 = 31541876
367 + 31541509 = 31541876

Showing the first eight; more decompositions exist.
