Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592080, here are decompositions:

29 + 31592051 = 31592080
41 + 31592039 = 31592080
83 + 31591997 = 31592080
101 + 31591979 = 31592080
167 + 31591913 = 31592080
347 + 31591733 = 31592080
431 + 31591649 = 31592080
479 + 31591601 = 31592080

Showing the first eight; more decompositions exist.
