Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541530, here are decompositions:

3 + 31541527 = 31541530
23 + 31541507 = 31541530
47 + 31541483 = 31541530
101 + 31541429 = 31541530
113 + 31541417 = 31541530
131 + 31541399 = 31541530
233 + 31541297 = 31541530
263 + 31541267 = 31541530

Showing the first eight; more decompositions exist.
