Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606462, here are decompositions:

89 + 31606373 = 31606462
131 + 31606331 = 31606462
149 + 31606313 = 31606462
179 + 31606283 = 31606462
281 + 31606181 = 31606462
383 + 31606079 = 31606462
401 + 31606061 = 31606462
479 + 31605983 = 31606462

Showing the first eight; more decompositions exist.
