Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294957990, here are decompositions:
- 17 + 4294957973 = 4294957990
- 47 + 4294957943 = 4294957990
- 131 + 4294957859 = 4294957990
- 137 + 4294957853 = 4294957990
- 149 + 4294957841 = 4294957990
- 293 + 4294957697 = 4294957990
- 311 + 4294957679 = 4294957990
- 347 + 4294957643 = 4294957990
Showing the first eight; more decompositions exist.
