Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 190618, here are decompositions:
- 5 + 190613 = 190618
- 11 + 190607 = 190618
- 41 + 190577 = 190618
- 89 + 190529 = 190618
- 227 + 190391 = 190618
- 251 + 190367 = 190618
- 317 + 190301 = 190618
- 347 + 190271 = 190618
Showing the first eight; more decompositions exist.
