Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33497640, here are decompositions:
- 17 + 33497623 = 33497640
- 31 + 33497609 = 33497640
- 37 + 33497603 = 33497640
- 47 + 33497593 = 33497640
- 61 + 33497579 = 33497640
- 73 + 33497567 = 33497640
- 79 + 33497561 = 33497640
- 157 + 33497483 = 33497640
Showing the first eight; more decompositions exist.
