Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592188, here are decompositions:

29 + 31592159 = 31592188
59 + 31592129 = 31592188
137 + 31592051 = 31592188
149 + 31592039 = 31592188
191 + 31591997 = 31592188
449 + 31591739 = 31592188
521 + 31591667 = 31592188
587 + 31591601 = 31592188

Showing the first eight; more decompositions exist.
