Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 752, here are decompositions:
- 13 + 739 = 752
- 19 + 733 = 752
- 43 + 709 = 752
- 61 + 691 = 752
- 79 + 673 = 752
- 109 + 643 = 752
- 139 + 613 = 752
- 151 + 601 = 752
Showing the first eight; more decompositions exist.
