Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33499872, here are decompositions:
- 31 + 33499841 = 33499872
- 59 + 33499813 = 33499872
- 71 + 33499801 = 33499872
- 83 + 33499789 = 33499872
- 89 + 33499783 = 33499872
- 101 + 33499771 = 33499872
- 103 + 33499769 = 33499872
- 113 + 33499759 = 33499872
Showing the first eight; more decompositions exist.
