Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145104, here are decompositions:
- 13 + 145091 = 145104
- 41 + 145063 = 145104
- 61 + 145043 = 145104
- 67 + 145037 = 145104
- 73 + 145031 = 145104
- 83 + 145021 = 145104
- 97 + 145007 = 145104
- 131 + 144973 = 145104
Showing the first eight; more decompositions exist.
