Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972156, here are decompositions:
- 5 + 4294972151 = 4294972156
- 47 + 4294972109 = 4294972156
- 107 + 4294972049 = 4294972156
- 227 + 4294971929 = 4294972156
- 593 + 4294971563 = 4294972156
- 599 + 4294971557 = 4294972156
- 653 + 4294971503 = 4294972156
- 659 + 4294971497 = 4294972156
Showing the first eight; more decompositions exist.
