Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170572, here are decompositions:
- 89 + 170483 = 170572
- 131 + 170441 = 170572
- 179 + 170393 = 170572
- 293 + 170279 = 170572
- 359 + 170213 = 170572
- 383 + 170189 = 170572
- 431 + 170141 = 170572
- 449 + 170123 = 170572
Showing the first eight; more decompositions exist.
