Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624562, here are decompositions:

3 + 31624559 = 31624562
139 + 31624423 = 31624562
199 + 31624363 = 31624562
223 + 31624339 = 31624562
241 + 31624321 = 31624562
421 + 31624141 = 31624562
433 + 31624129 = 31624562
631 + 31623931 = 31624562

Showing the first eight; more decompositions exist.
