Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294958138, here are decompositions:
- 7 + 4294958131 = 4294958138
- 61 + 4294958077 = 4294958138
- 67 + 4294958071 = 4294958138
- 127 + 4294958011 = 4294958138
- 181 + 4294957957 = 4294958138
- 199 + 4294957939 = 4294958138
- 277 + 4294957861 = 4294958138
- 409 + 4294957729 = 4294958138
Showing the first eight; more decompositions exist.
