Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26478, here are decompositions:
- 19 + 26459 = 26478
- 29 + 26449 = 26478
- 41 + 26437 = 26478
- 47 + 26431 = 26478
- 61 + 26417 = 26478
- 71 + 26407 = 26478
- 79 + 26399 = 26478
- 107 + 26371 = 26478
Showing the first eight; more decompositions exist.
