Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72988, here are decompositions:
- 11 + 72977 = 72988
- 29 + 72959 = 72988
- 191 + 72797 = 72988
- 269 + 72719 = 72988
- 281 + 72707 = 72988
- 317 + 72671 = 72988
- 491 + 72497 = 72988
- 521 + 72467 = 72988
Showing the first eight; more decompositions exist.
