Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588002, here are decompositions:

23 + 31587979 = 31588002
41 + 31587961 = 31588002
53 + 31587949 = 31588002
59 + 31587943 = 31588002
79 + 31587923 = 31588002
109 + 31587893 = 31588002
223 + 31587779 = 31588002
379 + 31587623 = 31588002

Showing the first eight; more decompositions exist.
