Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541804, here are decompositions:

43 + 31541761 = 31541804
67 + 31541737 = 31541804
97 + 31541707 = 31541804
127 + 31541677 = 31541804
193 + 31541611 = 31541804
223 + 31541581 = 31541804
241 + 31541563 = 31541804
277 + 31541527 = 31541804

Showing the first eight; more decompositions exist.
