Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592502, here are decompositions:

13 + 31592489 = 31592502
79 + 31592423 = 31592502
113 + 31592389 = 31592502
191 + 31592311 = 31592502
211 + 31592291 = 31592502
283 + 31592219 = 31592502
353 + 31592149 = 31592502
373 + 31592129 = 31592502

Showing the first eight; more decompositions exist.
