Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33477780, here are decompositions:
- 67 + 33477713 = 33477780
- 97 + 33477683 = 33477780
- 101 + 33477679 = 33477780
- 131 + 33477649 = 33477780
- 137 + 33477643 = 33477780
- 181 + 33477599 = 33477780
- 227 + 33477553 = 33477780
- 257 + 33477523 = 33477780
Showing the first eight; more decompositions exist.
