Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532548, here are decompositions:

41 + 31532507 = 31532548
59 + 31532489 = 31532548
71 + 31532477 = 31532548
269 + 31532279 = 31532548
431 + 31532117 = 31532548
617 + 31531931 = 31532548
797 + 31531751 = 31532548
821 + 31531727 = 31532548

Showing the first eight; more decompositions exist.
