Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498702, here are decompositions:
- 173 + 31498529 = 31498702
- 233 + 31498469 = 31498702
- 239 + 31498463 = 31498702
- 281 + 31498421 = 31498702
- 353 + 31498349 = 31498702
- 359 + 31498343 = 31498702
- 449 + 31498253 = 31498702
- 503 + 31498199 = 31498702
Showing the first eight; more decompositions exist.
