Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42144, here are decompositions:
- 5 + 42139 = 42144
- 13 + 42131 = 42144
- 43 + 42101 = 42144
- 61 + 42083 = 42144
- 71 + 42073 = 42144
- 73 + 42071 = 42144
- 83 + 42061 = 42144
- 101 + 42043 = 42144
Showing the first eight; more decompositions exist.
