Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84278, here are decompositions:
- 31 + 84247 = 84278
- 67 + 84211 = 84278
- 79 + 84199 = 84278
- 97 + 84181 = 84278
- 151 + 84127 = 84278
- 157 + 84121 = 84278
- 211 + 84067 = 84278
- 367 + 83911 = 84278
Showing the first eight; more decompositions exist.
