Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72746, here are decompositions:
- 7 + 72739 = 72746
- 13 + 72733 = 72746
- 19 + 72727 = 72746
- 67 + 72679 = 72746
- 73 + 72673 = 72746
- 97 + 72649 = 72746
- 103 + 72643 = 72746
- 199 + 72547 = 72746
Showing the first eight; more decompositions exist.
