Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12102, here are decompositions:
- 5 + 12097 = 12102
- 29 + 12073 = 12102
- 31 + 12071 = 12102
- 53 + 12049 = 12102
- 59 + 12043 = 12102
- 61 + 12041 = 12102
- 131 + 11971 = 12102
- 149 + 11953 = 12102
Showing the first eight; more decompositions exist.
