Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31038, here are decompositions:

5 + 31033 = 31038
19 + 31019 = 31038
61 + 30977 = 31038
67 + 30971 = 31038
89 + 30949 = 31038
97 + 30941 = 31038
101 + 30937 = 31038
107 + 30931 = 31038

Showing the first eight; more decompositions exist.
