Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022580, here are decompositions:
- 7 + 1022573 = 1022580
- 61 + 1022519 = 1022580
- 67 + 1022513 = 1022580
- 71 + 1022509 = 1022580
- 73 + 1022507 = 1022580
- 79 + 1022501 = 1022580
- 89 + 1022491 = 1022580
- 113 + 1022467 = 1022580
Showing the first eight; more decompositions exist.
