Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12018, here are decompositions:
- 7 + 12011 = 12018
- 11 + 12007 = 12018
- 31 + 11987 = 12018
- 37 + 11981 = 12018
- 47 + 11971 = 12018
- 59 + 11959 = 12018
- 79 + 11939 = 12018
- 109 + 11909 = 12018
Showing the first eight; more decompositions exist.
