Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33537140, here are decompositions:

19 + 33537121 = 33537140
37 + 33537103 = 33537140
79 + 33537061 = 33537140
157 + 33536983 = 33537140
199 + 33536941 = 33537140
331 + 33536809 = 33537140
433 + 33536707 = 33537140
463 + 33536677 = 33537140

Showing the first eight; more decompositions exist.
