Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75042, here are decompositions:
- 5 + 75037 = 75042
- 13 + 75029 = 75042
- 29 + 75013 = 75042
- 31 + 75011 = 75042
- 83 + 74959 = 75042
- 101 + 74941 = 75042
- 109 + 74933 = 75042
- 113 + 74929 = 75042
Showing the first eight; more decompositions exist.
