Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592580, here are decompositions:

13 + 31592567 = 31592580
23 + 31592557 = 31592580
29 + 31592551 = 31592580
113 + 31592467 = 31592580
127 + 31592453 = 31592580
157 + 31592423 = 31592580
163 + 31592417 = 31592580
191 + 31592389 = 31592580

Showing the first eight; more decompositions exist.
