Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74072, here are decompositions:
- 73 + 73999 = 74072
- 223 + 73849 = 74072
- 373 + 73699 = 74072
- 379 + 73693 = 74072
- 421 + 73651 = 74072
- 463 + 73609 = 74072
- 601 + 73471 = 74072
- 613 + 73459 = 74072
Showing the first eight; more decompositions exist.
