Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294958238, here are decompositions:
- 41 + 4294958197 = 4294958238
- 107 + 4294958131 = 4294958238
- 139 + 4294958099 = 4294958238
- 167 + 4294958071 = 4294958238
- 211 + 4294958027 = 4294958238
- 227 + 4294958011 = 4294958238
- 281 + 4294957957 = 4294958238
- 379 + 4294957859 = 4294958238
Showing the first eight; more decompositions exist.
