Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1036640, here are decompositions:
- 61 + 1036579 = 1036640
- 79 + 1036561 = 1036640
- 103 + 1036537 = 1036640
- 109 + 1036531 = 1036640
- 127 + 1036513 = 1036640
- 181 + 1036459 = 1036640
- 229 + 1036411 = 1036640
- 271 + 1036369 = 1036640
Showing the first eight; more decompositions exist.
