Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487808, here are decompositions:

37 + 33487771 = 33487808
127 + 33487681 = 33487808
157 + 33487651 = 33487808
229 + 33487579 = 33487808
271 + 33487537 = 33487808
331 + 33487477 = 33487808
421 + 33487387 = 33487808
499 + 33487309 = 33487808

Showing the first eight; more decompositions exist.
