Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144936, here are decompositions:
- 5 + 144931 = 144936
- 19 + 144917 = 144936
- 37 + 144899 = 144936
- 47 + 144889 = 144936
- 53 + 144883 = 144936
- 89 + 144847 = 144936
- 97 + 144839 = 144936
- 107 + 144829 = 144936
Showing the first eight; more decompositions exist.
