Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592906, here are decompositions:

73 + 31592833 = 31592906
97 + 31592809 = 31592906
109 + 31592797 = 31592906
127 + 31592779 = 31592906
223 + 31592683 = 31592906
229 + 31592677 = 31592906
307 + 31592599 = 31592906
349 + 31592557 = 31592906

Showing the first eight; more decompositions exist.
