Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491580, here are decompositions:

11 + 33491569 = 33491580
13 + 33491567 = 33491580
19 + 33491561 = 33491580
37 + 33491543 = 33491580
43 + 33491537 = 33491580
47 + 33491533 = 33491580
113 + 33491467 = 33491580
139 + 33491441 = 33491580

Showing the first eight; more decompositions exist.
