Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487636, here are decompositions:

5 + 33487631 = 33487636
29 + 33487607 = 33487636
293 + 33487343 = 33487636
317 + 33487319 = 33487636
359 + 33487277 = 33487636
389 + 33487247 = 33487636
443 + 33487193 = 33487636
449 + 33487187 = 33487636

Showing the first eight; more decompositions exist.
