Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61406, here are decompositions:
- 3 + 61403 = 61406
- 43 + 61363 = 61406
- 67 + 61339 = 61406
- 73 + 61333 = 61406
- 109 + 61297 = 61406
- 277 + 61129 = 61406
- 307 + 61099 = 61406
- 349 + 61057 = 61406
Showing the first eight; more decompositions exist.
