Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84126, here are decompositions:
- 5 + 84121 = 84126
- 37 + 84089 = 84126
- 59 + 84067 = 84126
- 67 + 84059 = 84126
- 73 + 84053 = 84126
- 79 + 84047 = 84126
- 109 + 84017 = 84126
- 139 + 83987 = 84126
Showing the first eight; more decompositions exist.
