Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541170, here are decompositions:

29 + 31541141 = 31541170
41 + 31541129 = 31541170
53 + 31541117 = 31541170
131 + 31541039 = 31541170
149 + 31541021 = 31541170
179 + 31540991 = 31541170
191 + 31540979 = 31541170
347 + 31540823 = 31541170

Showing the first eight; more decompositions exist.
