Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542190, here are decompositions:
- 41 + 31542149 = 31542190
- 107 + 31542083 = 31542190
- 167 + 31542023 = 31542190
- 179 + 31542011 = 31542190
- 257 + 31541933 = 31542190
- 557 + 31541633 = 31542190
- 593 + 31541597 = 31542190
- 599 + 31541591 = 31542190
Showing the first eight; more decompositions exist.
