Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84156, here are decompositions:
- 13 + 84143 = 84156
- 19 + 84137 = 84156
- 29 + 84127 = 84156
- 67 + 84089 = 84156
- 89 + 84067 = 84156
- 97 + 84059 = 84156
- 103 + 84053 = 84156
- 109 + 84047 = 84156
Showing the first eight; more decompositions exist.
