Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624726, here are decompositions:

53 + 31624673 = 31624726
83 + 31624643 = 31624726
113 + 31624613 = 31624726
167 + 31624559 = 31624726
179 + 31624547 = 31624726
269 + 31624457 = 31624726
359 + 31624367 = 31624726
383 + 31624343 = 31624726

Showing the first eight; more decompositions exist.
