Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487812, here are decompositions:

41 + 33487771 = 33487812
53 + 33487759 = 33487812
79 + 33487733 = 33487812
131 + 33487681 = 33487812
173 + 33487639 = 33487812
181 + 33487631 = 33487812
191 + 33487621 = 33487812
233 + 33487579 = 33487812

Showing the first eight; more decompositions exist.
