Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83780, here are decompositions:
- 3 + 83777 = 83780
- 7 + 83773 = 83780
- 19 + 83761 = 83780
- 43 + 83737 = 83780
- 61 + 83719 = 83780
- 79 + 83701 = 83780
- 127 + 83653 = 83780
- 139 + 83641 = 83780
Showing the first eight; more decompositions exist.
