Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581066, here are decompositions:

73 + 33580993 = 33581066
109 + 33580957 = 33581066
157 + 33580909 = 33581066
163 + 33580903 = 33581066
373 + 33580693 = 33581066
397 + 33580669 = 33581066
433 + 33580633 = 33581066
577 + 33580489 = 33581066

Showing the first eight; more decompositions exist.
