Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531830, here are decompositions:

37 + 33531793 = 33531830
151 + 33531679 = 33531830
271 + 33531559 = 33531830
331 + 33531499 = 33531830
379 + 33531451 = 33531830
433 + 33531397 = 33531830
439 + 33531391 = 33531830
547 + 33531283 = 33531830

Showing the first eight; more decompositions exist.
