Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 120988, here are decompositions:
- 11 + 120977 = 120988
- 41 + 120947 = 120988
- 47 + 120941 = 120988
- 59 + 120929 = 120988
- 71 + 120917 = 120988
- 89 + 120899 = 120988
- 137 + 120851 = 120988
- 239 + 120749 = 120988
Showing the first eight; more decompositions exist.
