Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15042, here are decompositions:
- 11 + 15031 = 15042
- 29 + 15013 = 15042
- 59 + 14983 = 15042
- 73 + 14969 = 15042
- 103 + 14939 = 15042
- 113 + 14929 = 15042
- 151 + 14891 = 15042
- 163 + 14879 = 15042
Showing the first eight; more decompositions exist.
