Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15004, here are decompositions:
- 47 + 14957 = 15004
- 53 + 14951 = 15004
- 107 + 14897 = 15004
- 113 + 14891 = 15004
- 137 + 14867 = 15004
- 173 + 14831 = 15004
- 191 + 14813 = 15004
- 233 + 14771 = 15004
Showing the first eight; more decompositions exist.
