Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592492, here are decompositions:

3 + 31592489 = 31592492
103 + 31592389 = 31592492
181 + 31592311 = 31592492
331 + 31592161 = 31592492
439 + 31592053 = 31592492
499 + 31591993 = 31592492
619 + 31591873 = 31592492
709 + 31591783 = 31592492

Showing the first eight; more decompositions exist.
