Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031820, here are decompositions:
- 7 + 1031813 = 1031820
- 11 + 1031809 = 1031820
- 59 + 1031761 = 1031820
- 61 + 1031759 = 1031820
- 67 + 1031753 = 1031820
- 79 + 1031741 = 1031820
- 89 + 1031731 = 1031820
- 103 + 1031717 = 1031820
Showing the first eight; more decompositions exist.
