Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 98042, here are decompositions:
- 31 + 98011 = 98042
- 163 + 97879 = 98042
- 181 + 97861 = 98042
- 193 + 97849 = 98042
- 199 + 97843 = 98042
- 229 + 97813 = 98042
- 271 + 97771 = 98042
- 313 + 97729 = 98042
Showing the first eight; more decompositions exist.
