Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535552, here are decompositions:

3 + 31535549 = 31535552
211 + 31535341 = 31535552
241 + 31535311 = 31535552
379 + 31535173 = 31535552
409 + 31535143 = 31535552
421 + 31535131 = 31535552
439 + 31535113 = 31535552
541 + 31535011 = 31535552

Showing the first eight; more decompositions exist.
