Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489106, here are decompositions:

37 + 31489069 = 31489106
43 + 31489063 = 31489106
79 + 31489027 = 31489106
97 + 31489009 = 31489106
127 + 31488979 = 31489106
199 + 31488907 = 31489106
307 + 31488799 = 31489106
373 + 31488733 = 31489106

Showing the first eight; more decompositions exist.
