Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72752, here are decompositions:
- 13 + 72739 = 72752
- 19 + 72733 = 72752
- 73 + 72679 = 72752
- 79 + 72673 = 72752
- 103 + 72649 = 72752
- 109 + 72643 = 72752
- 139 + 72613 = 72752
- 193 + 72559 = 72752
Showing the first eight; more decompositions exist.
