Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541024, here are decompositions:

3 + 31541021 = 31541024
7 + 31541017 = 31541024
103 + 31540921 = 31541024
157 + 31540867 = 31541024
211 + 31540813 = 31541024
241 + 31540783 = 31541024
331 + 31540693 = 31541024
367 + 31540657 = 31541024

Showing the first eight; more decompositions exist.
