Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592910, here are decompositions:

61 + 31592849 = 31592910
67 + 31592843 = 31592910
101 + 31592809 = 31592910
113 + 31592797 = 31592910
131 + 31592779 = 31592910
137 + 31592773 = 31592910
149 + 31592761 = 31592910
163 + 31592747 = 31592910

Showing the first eight; more decompositions exist.
