Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87126, here are decompositions:
- 5 + 87121 = 87126
- 7 + 87119 = 87126
- 19 + 87107 = 87126
- 23 + 87103 = 87126
- 43 + 87083 = 87126
- 89 + 87037 = 87126
- 113 + 87013 = 87126
- 157 + 86969 = 87126
Showing the first eight; more decompositions exist.
