Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85042, here are decompositions:
- 5 + 85037 = 85042
- 173 + 84869 = 85042
- 233 + 84809 = 85042
- 281 + 84761 = 85042
- 311 + 84731 = 85042
- 383 + 84659 = 85042
- 389 + 84653 = 85042
- 491 + 84551 = 85042
Showing the first eight; more decompositions exist.
