Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624592, here are decompositions:

163 + 31624429 = 31624592
229 + 31624363 = 31624592
271 + 31624321 = 31624592
463 + 31624129 = 31624592
523 + 31624069 = 31624592
613 + 31623979 = 31624592
661 + 31623931 = 31624592
691 + 31623901 = 31624592

Showing the first eight; more decompositions exist.
