Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84380, here are decompositions:
- 3 + 84377 = 84380
- 31 + 84349 = 84380
- 61 + 84319 = 84380
- 67 + 84313 = 84380
- 73 + 84307 = 84380
- 151 + 84229 = 84380
- 157 + 84223 = 84380
- 181 + 84199 = 84380
Showing the first eight; more decompositions exist.
