Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462162, here are decompositions:

29 + 31462133 = 31462162
59 + 31462103 = 31462162
239 + 31461923 = 31462162
269 + 31461893 = 31462162
311 + 31461851 = 31462162
383 + 31461779 = 31462162
401 + 31461761 = 31462162
419 + 31461743 = 31462162

Showing the first eight; more decompositions exist.
