Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592562, here are decompositions:

5 + 31592557 = 31592562
11 + 31592551 = 31592562
31 + 31592531 = 31592562
73 + 31592489 = 31592562
109 + 31592453 = 31592562
139 + 31592423 = 31592562
151 + 31592411 = 31592562
173 + 31592389 = 31592562

Showing the first eight; more decompositions exist.
