Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61672, here are decompositions:
- 5 + 61667 = 61672
- 29 + 61643 = 61672
- 41 + 61631 = 61672
- 59 + 61613 = 61672
- 89 + 61583 = 61672
- 113 + 61559 = 61672
- 179 + 61493 = 61672
- 263 + 61409 = 61672
Showing the first eight; more decompositions exist.
