Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541142, here are decompositions:

13 + 31541129 = 31541142
29 + 31541113 = 31541142
41 + 31541101 = 31541142
71 + 31541071 = 31541142
103 + 31541039 = 31541142
151 + 31540991 = 31541142
163 + 31540979 = 31541142
181 + 31540961 = 31541142

Showing the first eight; more decompositions exist.
