Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61478, here are decompositions:
- 7 + 61471 = 61478
- 37 + 61441 = 61478
- 61 + 61417 = 61478
- 97 + 61381 = 61478
- 139 + 61339 = 61478
- 181 + 61297 = 61478
- 337 + 61141 = 61478
- 349 + 61129 = 61478
Showing the first eight; more decompositions exist.
