Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42102, here are decompositions:
- 13 + 42089 = 42102
- 19 + 42083 = 42102
- 29 + 42073 = 42102
- 31 + 42071 = 42102
- 41 + 42061 = 42102
- 59 + 42043 = 42102
- 79 + 42023 = 42102
- 83 + 42019 = 42102
Showing the first eight; more decompositions exist.
