Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531838, here are decompositions:

47 + 33531791 = 33531838
89 + 33531749 = 33531838
101 + 33531737 = 33531838
167 + 33531671 = 33531838
227 + 33531611 = 33531838
251 + 33531587 = 33531838
311 + 33531527 = 33531838
359 + 33531479 = 33531838

Showing the first eight; more decompositions exist.
