Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491520, here are decompositions:
- 31 + 33491489 = 33491520
- 53 + 33491467 = 33491520
- 59 + 33491461 = 33491520
- 61 + 33491459 = 33491520
- 79 + 33491441 = 33491520
- 103 + 33491417 = 33491520
- 149 + 33491371 = 33491520
- 151 + 33491369 = 33491520
Showing the first eight; more decompositions exist.
