Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294958990, here are decompositions:
- 61 + 4294958929 = 4294958990
- 67 + 4294958923 = 4294958990
- 103 + 4294958887 = 4294958990
- 109 + 4294958881 = 4294958990
- 199 + 4294958791 = 4294958990
- 373 + 4294958617 = 4294958990
- 379 + 4294958611 = 4294958990
- 463 + 4294958527 = 4294958990
Showing the first eight; more decompositions exist.
