Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513070, here are decompositions:
- 7 + 31513063 = 31513070
- 13 + 31513057 = 31513070
- 37 + 31513033 = 31513070
- 67 + 31513003 = 31513070
- 73 + 31512997 = 31513070
- 79 + 31512991 = 31513070
- 157 + 31512913 = 31513070
- 163 + 31512907 = 31513070
Showing the first eight; more decompositions exist.
