Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588062, here are decompositions:

43 + 31588019 = 31588062
59 + 31588003 = 31588062
83 + 31587979 = 31588062
101 + 31587961 = 31588062
113 + 31587949 = 31588062
139 + 31587923 = 31588062
151 + 31587911 = 31588062
263 + 31587799 = 31588062

Showing the first eight; more decompositions exist.
