Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77540, here are decompositions:
- 13 + 77527 = 77540
- 19 + 77521 = 77540
- 31 + 77509 = 77540
- 61 + 77479 = 77540
- 109 + 77431 = 77540
- 157 + 77383 = 77540
- 163 + 77377 = 77540
- 181 + 77359 = 77540
Showing the first eight; more decompositions exist.
