Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72488, here are decompositions:
- 7 + 72481 = 72488
- 19 + 72469 = 72488
- 67 + 72421 = 72488
- 109 + 72379 = 72488
- 151 + 72337 = 72488
- 181 + 72307 = 72488
- 211 + 72277 = 72488
- 277 + 72211 = 72488
Showing the first eight; more decompositions exist.
