Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78486, here are decompositions:
- 7 + 78479 = 78486
- 19 + 78467 = 78486
- 47 + 78439 = 78486
- 59 + 78427 = 78486
- 139 + 78347 = 78486
- 179 + 78307 = 78486
- 227 + 78259 = 78486
- 257 + 78229 = 78486
Showing the first eight; more decompositions exist.
