Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450198, here are decompositions:
- 137 + 31450061 = 31450198
- 167 + 31450031 = 31450198
- 431 + 31449767 = 31450198
- 509 + 31449689 = 31450198
- 569 + 31449629 = 31450198
- 587 + 31449611 = 31450198
- 617 + 31449581 = 31450198
- 641 + 31449557 = 31450198
Showing the first eight; more decompositions exist.
