Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462300, here are decompositions:

11 + 31462289 = 31462300
83 + 31462217 = 31462300
167 + 31462133 = 31462300
173 + 31462127 = 31462300
197 + 31462103 = 31462300
293 + 31462007 = 31462300
449 + 31461851 = 31462300
509 + 31461791 = 31462300

Showing the first eight; more decompositions exist.
