Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592814, here are decompositions:

5 + 31592809 = 31592814
17 + 31592797 = 31592814
41 + 31592773 = 31592814
53 + 31592761 = 31592814
67 + 31592747 = 31592814
131 + 31592683 = 31592814
137 + 31592677 = 31592814
151 + 31592663 = 31592814

Showing the first eight; more decompositions exist.
