Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76640, here are decompositions:
- 37 + 76603 = 76640
- 43 + 76597 = 76640
- 61 + 76579 = 76640
- 79 + 76561 = 76640
- 97 + 76543 = 76640
- 103 + 76537 = 76640
- 199 + 76441 = 76640
- 271 + 76369 = 76640
Showing the first eight; more decompositions exist.
