Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624048, here are decompositions:

47 + 31624001 = 31624048
59 + 31623989 = 31624048
89 + 31623959 = 31624048
101 + 31623947 = 31624048
191 + 31623857 = 31624048
227 + 31623821 = 31624048
251 + 31623797 = 31624048
317 + 31623731 = 31624048

Showing the first eight; more decompositions exist.
