Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489088, here are decompositions:

19 + 31489069 = 31489088
61 + 31489027 = 31489088
79 + 31489009 = 31489088
97 + 31488991 = 31489088
109 + 31488979 = 31489088
157 + 31488931 = 31489088
181 + 31488907 = 31489088
229 + 31488859 = 31489088

Showing the first eight; more decompositions exist.
