Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294977990, here are decompositions:
- 29 + 4294977961 = 4294977990
- 47 + 4294977943 = 4294977990
- 97 + 4294977893 = 4294977990
- 109 + 4294977881 = 4294977990
- 131 + 4294977859 = 4294977990
- 151 + 4294977839 = 4294977990
- 167 + 4294977823 = 4294977990
- 197 + 4294977793 = 4294977990
Showing the first eight; more decompositions exist.
