Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148920, here are decompositions:
- 7 + 148913 = 148920
- 29 + 148891 = 148920
- 47 + 148873 = 148920
- 53 + 148867 = 148920
- 59 + 148861 = 148920
- 61 + 148859 = 148920
- 67 + 148853 = 148920
- 103 + 148817 = 148920
Showing the first eight; more decompositions exist.
