Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498630, here are decompositions:
- 71 + 31498559 = 31498630
- 83 + 31498547 = 31498630
- 89 + 31498541 = 31498630
- 101 + 31498529 = 31498630
- 113 + 31498517 = 31498630
- 131 + 31498499 = 31498630
- 167 + 31498463 = 31498630
- 263 + 31498367 = 31498630
Showing the first eight; more decompositions exist.
