Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33619940, here are decompositions:

97 + 33619843 = 33619940
139 + 33619801 = 33619940
271 + 33619669 = 33619940
313 + 33619627 = 33619940
337 + 33619603 = 33619940
379 + 33619561 = 33619940
499 + 33619441 = 33619940
643 + 33619297 = 33619940

Showing the first eight; more decompositions exist.
