Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72648, here are decompositions:
- 5 + 72643 = 72648
- 31 + 72617 = 72648
- 71 + 72577 = 72648
- 89 + 72559 = 72648
- 97 + 72551 = 72648
- 101 + 72547 = 72648
- 151 + 72497 = 72648
- 167 + 72481 = 72648
Showing the first eight; more decompositions exist.
