Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619250, here are decompositions:
- 37 + 31619213 = 31619250
- 41 + 31619209 = 31619250
- 43 + 31619207 = 31619250
- 59 + 31619191 = 31619250
- 67 + 31619183 = 31619250
- 71 + 31619179 = 31619250
- 73 + 31619177 = 31619250
- 79 + 31619171 = 31619250
Showing the first eight; more decompositions exist.
