Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42098, here are decompositions:
- 37 + 42061 = 42098
- 79 + 42019 = 42098
- 139 + 41959 = 42098
- 151 + 41947 = 42098
- 157 + 41941 = 42098
- 211 + 41887 = 42098
- 337 + 41761 = 42098
- 379 + 41719 = 42098
Showing the first eight; more decompositions exist.
