Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483190, here are decompositions:
- 73 + 31483117 = 31483190
- 97 + 31483093 = 31483190
- 103 + 31483087 = 31483190
- 139 + 31483051 = 31483190
- 199 + 31482991 = 31483190
- 283 + 31482907 = 31483190
- 331 + 31482859 = 31483190
- 367 + 31482823 = 31483190
Showing the first eight; more decompositions exist.
