Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489122, here are decompositions:

31 + 31489091 = 31489122
43 + 31489079 = 31489122
53 + 31489069 = 31489122
59 + 31489063 = 31489122
79 + 31489043 = 31489122
113 + 31489009 = 31489122
131 + 31488991 = 31489122
151 + 31488971 = 31489122

Showing the first eight; more decompositions exist.
