Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462282, here are decompositions:

149 + 31462133 = 31462282
179 + 31462103 = 31462282
359 + 31461923 = 31462282
389 + 31461893 = 31462282
431 + 31461851 = 31462282
491 + 31461791 = 31462282
503 + 31461779 = 31462282
521 + 31461761 = 31462282

Showing the first eight; more decompositions exist.
