Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179172, here are decompositions:
- 5 + 179167 = 179172
- 11 + 179161 = 179172
- 29 + 179143 = 179172
- 53 + 179119 = 179172
- 61 + 179111 = 179172
- 73 + 179099 = 179172
- 83 + 179089 = 179172
- 89 + 179083 = 179172
Showing the first eight; more decompositions exist.
