Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618932, here are decompositions:

31 + 31618901 = 31618932
41 + 31618891 = 31618932
53 + 31618879 = 31618932
61 + 31618871 = 31618932
83 + 31618849 = 31618932
109 + 31618823 = 31618932
113 + 31618819 = 31618932
151 + 31618781 = 31618932

Showing the first eight; more decompositions exist.
