Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84138, here are decompositions:
- 7 + 84131 = 84138
- 11 + 84127 = 84138
- 17 + 84121 = 84138
- 71 + 84067 = 84138
- 79 + 84059 = 84138
- 127 + 84011 = 84138
- 151 + 83987 = 84138
- 199 + 83939 = 84138
Showing the first eight; more decompositions exist.
