Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487902, here are decompositions:

43 + 33487859 = 33487902
83 + 33487819 = 33487902
89 + 33487813 = 33487902
131 + 33487771 = 33487902
251 + 33487651 = 33487902
263 + 33487639 = 33487902
271 + 33487631 = 33487902
281 + 33487621 = 33487902

Showing the first eight; more decompositions exist.
