Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170624, here are decompositions:
- 67 + 170557 = 170624
- 73 + 170551 = 170624
- 127 + 170497 = 170624
- 151 + 170473 = 170624
- 211 + 170413 = 170624
- 241 + 170383 = 170624
- 271 + 170353 = 170624
- 277 + 170347 = 170624
Showing the first eight; more decompositions exist.
