Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152782, here are decompositions:
- 5 + 152777 = 152782
- 29 + 152753 = 152782
- 53 + 152729 = 152782
- 59 + 152723 = 152782
- 101 + 152681 = 152782
- 251 + 152531 = 152782
- 263 + 152519 = 152782
- 281 + 152501 = 152782
Showing the first eight; more decompositions exist.
