Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489092, here are decompositions:

13 + 31489079 = 31489092
23 + 31489069 = 31489092
29 + 31489063 = 31489092
83 + 31489009 = 31489092
101 + 31488991 = 31489092
113 + 31488979 = 31489092
181 + 31488911 = 31489092
233 + 31488859 = 31489092

Showing the first eight; more decompositions exist.
