Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612350, here are decompositions:
- 37 + 31612313 = 31612350
- 41 + 31612309 = 31612350
- 43 + 31612307 = 31612350
- 73 + 31612277 = 31612350
- 109 + 31612241 = 31612350
- 127 + 31612223 = 31612350
- 149 + 31612201 = 31612350
- 151 + 31612199 = 31612350
Showing the first eight; more decompositions exist.
