Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30144, here are decompositions:
- 5 + 30139 = 30144
- 7 + 30137 = 30144
- 11 + 30133 = 30144
- 31 + 30113 = 30144
- 41 + 30103 = 30144
- 47 + 30097 = 30144
- 53 + 30091 = 30144
- 73 + 30071 = 30144
Showing the first eight; more decompositions exist.
