Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163170, here are decompositions:
- 19 + 163151 = 163170
- 23 + 163147 = 163170
- 41 + 163129 = 163170
- 43 + 163127 = 163170
- 53 + 163117 = 163170
- 61 + 163109 = 163170
- 107 + 163063 = 163170
- 109 + 163061 = 163170
Showing the first eight; more decompositions exist.
