Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89438, here are decompositions:
- 7 + 89431 = 89438
- 67 + 89371 = 89438
- 109 + 89329 = 89438
- 211 + 89227 = 89438
- 229 + 89209 = 89438
- 331 + 89107 = 89438
- 337 + 89101 = 89438
- 367 + 89071 = 89438
Showing the first eight; more decompositions exist.
