Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170478, here are decompositions:
- 5 + 170473 = 170478
- 31 + 170447 = 170478
- 37 + 170441 = 170478
- 89 + 170389 = 170478
- 107 + 170371 = 170478
- 109 + 170369 = 170478
- 127 + 170351 = 170478
- 131 + 170347 = 170478
Showing the first eight; more decompositions exist.
