Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533526, here are decompositions:

29 + 31533497 = 31533526
113 + 31533413 = 31533526
137 + 31533389 = 31533526
257 + 31533269 = 31533526
317 + 31533209 = 31533526
359 + 31533167 = 31533526
383 + 31533143 = 31533526
587 + 31532939 = 31533526

Showing the first eight; more decompositions exist.
