Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177390, here are decompositions:
- 7 + 177383 = 177390
- 11 + 177379 = 177390
- 43 + 177347 = 177390
- 53 + 177337 = 177390
- 67 + 177323 = 177390
- 71 + 177319 = 177390
- 89 + 177301 = 177390
- 107 + 177283 = 177390
Showing the first eight; more decompositions exist.
