Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533490, here are decompositions:

29 + 31533461 = 31533490
41 + 31533449 = 31533490
59 + 31533431 = 31533490
101 + 31533389 = 31533490
281 + 31533209 = 31533490
347 + 31533143 = 31533490
389 + 31533101 = 31533490
491 + 31532999 = 31533490

Showing the first eight; more decompositions exist.
