Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528248, here are decompositions:

7 + 31528241 = 31528248
19 + 31528229 = 31528248
41 + 31528207 = 31528248
79 + 31528169 = 31528248
97 + 31528151 = 31528248
127 + 31528121 = 31528248
137 + 31528111 = 31528248
179 + 31528069 = 31528248

Showing the first eight; more decompositions exist.
