Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86988, here are decompositions:
- 7 + 86981 = 86988
- 19 + 86969 = 86988
- 29 + 86959 = 86988
- 37 + 86951 = 86988
- 59 + 86929 = 86988
- 61 + 86927 = 86988
- 127 + 86861 = 86988
- 131 + 86857 = 86988
Showing the first eight; more decompositions exist.
