Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592874, here are decompositions:

31 + 31592843 = 31592874
41 + 31592833 = 31592874
101 + 31592773 = 31592874
113 + 31592761 = 31592874
127 + 31592747 = 31592874
191 + 31592683 = 31592874
197 + 31592677 = 31592874
211 + 31592663 = 31592874

Showing the first eight; more decompositions exist.
