Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87022, here are decompositions:
- 11 + 87011 = 87022
- 29 + 86993 = 87022
- 41 + 86981 = 87022
- 53 + 86969 = 87022
- 71 + 86951 = 87022
- 83 + 86939 = 87022
- 179 + 86843 = 87022
- 239 + 86783 = 87022
Showing the first eight; more decompositions exist.
