Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77442, here are decompositions:
- 11 + 77431 = 77442
- 23 + 77419 = 77442
- 59 + 77383 = 77442
- 73 + 77369 = 77442
- 83 + 77359 = 77442
- 103 + 77339 = 77442
- 151 + 77291 = 77442
- 163 + 77279 = 77442
Showing the first eight; more decompositions exist.
