Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541052, here are decompositions:

5 + 31541047 = 31541052
13 + 31541039 = 31541052
31 + 31541021 = 31541052
61 + 31540991 = 31541052
73 + 31540979 = 31541052
113 + 31540939 = 31541052
131 + 31540921 = 31541052
181 + 31540871 = 31541052

Showing the first eight; more decompositions exist.
