Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148520, here are decompositions:
- 3 + 148517 = 148520
- 7 + 148513 = 148520
- 19 + 148501 = 148520
- 37 + 148483 = 148520
- 109 + 148411 = 148520
- 139 + 148381 = 148520
- 181 + 148339 = 148520
- 241 + 148279 = 148520
Showing the first eight; more decompositions exist.
