Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624302, here are decompositions:

19 + 31624283 = 31624302
173 + 31624129 = 31624302
233 + 31624069 = 31624302
313 + 31623989 = 31624302
331 + 31623971 = 31624302
349 + 31623953 = 31624302
373 + 31623929 = 31624302
401 + 31623901 = 31624302

Showing the first eight; more decompositions exist.
