Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104642, here are decompositions:
- 3 + 104639 = 104642
- 19 + 104623 = 104642
- 151 + 104491 = 104642
- 163 + 104479 = 104642
- 331 + 104311 = 104642
- 409 + 104233 = 104642
- 463 + 104179 = 104642
- 523 + 104119 = 104642
Showing the first eight; more decompositions exist.
