Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89442, here are decompositions:
- 11 + 89431 = 89442
- 29 + 89413 = 89442
- 43 + 89399 = 89442
- 61 + 89381 = 89442
- 71 + 89371 = 89442
- 79 + 89363 = 89442
- 113 + 89329 = 89442
- 139 + 89303 = 89442
Showing the first eight; more decompositions exist.
