Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624088, here are decompositions:

19 + 31624069 = 31624088
109 + 31623979 = 31624088
157 + 31623931 = 31624088
271 + 31623817 = 31624088
367 + 31623721 = 31624088
421 + 31623667 = 31624088
499 + 31623589 = 31624088
577 + 31623511 = 31624088

Showing the first eight; more decompositions exist.
