Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592012, here are decompositions:

13 + 31591999 = 31592012
19 + 31591993 = 31592012
103 + 31591909 = 31592012
139 + 31591873 = 31592012
229 + 31591783 = 31592012
409 + 31591603 = 31592012
499 + 31591513 = 31592012
631 + 31591381 = 31592012

Showing the first eight; more decompositions exist.
