Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148622, here are decompositions:
- 13 + 148609 = 148622
- 43 + 148579 = 148622
- 73 + 148549 = 148622
- 109 + 148513 = 148622
- 139 + 148483 = 148622
- 151 + 148471 = 148622
- 193 + 148429 = 148622
- 211 + 148411 = 148622
Showing the first eight; more decompositions exist.
