Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170578, here are decompositions:
- 41 + 170537 = 170578
- 131 + 170447 = 170578
- 137 + 170441 = 170578
- 227 + 170351 = 170578
- 251 + 170327 = 170578
- 311 + 170267 = 170578
- 347 + 170231 = 170578
- 389 + 170189 = 170578
Showing the first eight; more decompositions exist.
