Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84978, here are decompositions:
- 11 + 84967 = 84978
- 17 + 84961 = 84978
- 31 + 84947 = 84978
- 59 + 84919 = 84978
- 107 + 84871 = 84978
- 109 + 84869 = 84978
- 151 + 84827 = 84978
- 167 + 84811 = 84978
Showing the first eight; more decompositions exist.
