Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 190378, here are decompositions:
- 11 + 190367 = 190378
- 47 + 190331 = 190378
- 107 + 190271 = 190378
- 197 + 190181 = 190378
- 257 + 190121 = 190378
- 281 + 190097 = 190378
- 347 + 190031 = 190378
- 389 + 189989 = 190378
Showing the first eight; more decompositions exist.
