Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31505046, here are decompositions:

7 + 31505039 = 31505046
19 + 31505027 = 31505046
43 + 31505003 = 31505046
47 + 31504999 = 31505046
59 + 31504987 = 31505046
103 + 31504943 = 31505046
137 + 31504909 = 31505046
163 + 31504883 = 31505046

Showing the first eight; more decompositions exist.
