Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15142, here are decompositions:
- 3 + 15139 = 15142
- 5 + 15137 = 15142
- 11 + 15131 = 15142
- 41 + 15101 = 15142
- 59 + 15083 = 15142
- 89 + 15053 = 15142
- 173 + 14969 = 15142
- 191 + 14951 = 15142
Showing the first eight; more decompositions exist.
