Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526580, here are decompositions:

17 + 31526563 = 31526580
47 + 31526533 = 31526580
53 + 31526527 = 31526580
83 + 31526497 = 31526580
103 + 31526477 = 31526580
149 + 31526431 = 31526580
157 + 31526423 = 31526580
191 + 31526389 = 31526580

Showing the first eight; more decompositions exist.
