Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487900, here are decompositions:

23 + 33487877 = 33487900
41 + 33487859 = 33487900
53 + 33487847 = 33487900
167 + 33487733 = 33487900
269 + 33487631 = 33487900
293 + 33487607 = 33487900
389 + 33487511 = 33487900
449 + 33487451 = 33487900

Showing the first eight; more decompositions exist.
