Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68150, here are decompositions:
- 3 + 68147 = 68150
- 37 + 68113 = 68150
- 79 + 68071 = 68150
- 97 + 68053 = 68150
- 109 + 68041 = 68150
- 127 + 68023 = 68150
- 157 + 67993 = 68150
- 163 + 67987 = 68150
Showing the first eight; more decompositions exist.
