Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462186, here are decompositions:

53 + 31462133 = 31462186
59 + 31462127 = 31462186
83 + 31462103 = 31462186
179 + 31462007 = 31462186
263 + 31461923 = 31462186
293 + 31461893 = 31462186
443 + 31461743 = 31462186
449 + 31461737 = 31462186

Showing the first eight; more decompositions exist.
