Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42650, here are decompositions:
- 7 + 42643 = 42650
- 61 + 42589 = 42650
- 73 + 42577 = 42650
- 79 + 42571 = 42650
- 151 + 42499 = 42650
- 163 + 42487 = 42650
- 193 + 42457 = 42650
- 199 + 42451 = 42650
Showing the first eight; more decompositions exist.
