Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581982, here are decompositions:

61 + 33581921 = 33581982
113 + 33581869 = 33581982
163 + 33581819 = 33581982
191 + 33581791 = 33581982
241 + 33581741 = 33581982
311 + 33581671 = 33581982
383 + 33581599 = 33581982
409 + 33581573 = 33581982

Showing the first eight; more decompositions exist.
