Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540988, here are decompositions:
- 137 + 540851 = 540988
- 179 + 540809 = 540988
- 311 + 540677 = 540988
- 359 + 540629 = 540988
- 389 + 540599 = 540988
- 401 + 540587 = 540988
- 431 + 540557 = 540988
- 449 + 540539 = 540988
Showing the first eight; more decompositions exist.
