Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294957640, here are decompositions:
- 31 + 4294957609 = 4294957640
- 241 + 4294957399 = 4294957640
- 271 + 4294957369 = 4294957640
- 331 + 4294957309 = 4294957640
- 373 + 4294957267 = 4294957640
- 433 + 4294957207 = 4294957640
- 541 + 4294957099 = 4294957640
- 691 + 4294956949 = 4294957640
Showing the first eight; more decompositions exist.
