Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147172, here are decompositions:
- 83 + 147089 = 147172
- 89 + 147083 = 147172
- 239 + 146933 = 147172
- 251 + 146921 = 147172
- 281 + 146891 = 147172
- 353 + 146819 = 147172
- 491 + 146681 = 147172
- 503 + 146669 = 147172
Showing the first eight; more decompositions exist.
