Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527714, here are decompositions:

5 + 31527709 = 31527714
11 + 31527703 = 31527714
13 + 31527701 = 31527714
17 + 31527697 = 31527714
37 + 31527677 = 31527714
131 + 31527583 = 31527714
137 + 31527577 = 31527714
173 + 31527541 = 31527714

Showing the first eight; more decompositions exist.

IPv4 address
