Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89172, here are decompositions:
- 19 + 89153 = 89172
- 53 + 89119 = 89172
- 59 + 89113 = 89172
- 71 + 89101 = 89172
- 89 + 89083 = 89172
- 101 + 89071 = 89172
- 103 + 89069 = 89172
- 131 + 89041 = 89172
Showing the first eight; more decompositions exist.
