Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514616, here are decompositions:
- 17 + 31514599 = 31514616
- 37 + 31514579 = 31514616
- 43 + 31514573 = 31514616
- 79 + 31514537 = 31514616
- 83 + 31514533 = 31514616
- 103 + 31514513 = 31514616
- 137 + 31514479 = 31514616
- 139 + 31514477 = 31514616
Showing the first eight; more decompositions exist.
