Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541080, here are decompositions:

29 + 31541051 = 31541080
41 + 31541039 = 31541080
59 + 31541021 = 31541080
89 + 31540991 = 31541080
101 + 31540979 = 31541080
257 + 31540823 = 31541080
293 + 31540787 = 31541080
353 + 31540727 = 31541080

Showing the first eight; more decompositions exist.
