Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148928, here are decompositions:
- 7 + 148921 = 148928
- 37 + 148891 = 148928
- 61 + 148867 = 148928
- 67 + 148861 = 148928
- 181 + 148747 = 148928
- 349 + 148579 = 148928
- 379 + 148549 = 148928
- 397 + 148531 = 148928
Showing the first eight; more decompositions exist.
