Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602248, here are decompositions:

31 + 31602217 = 31602248
127 + 31602121 = 31602248
151 + 31602097 = 31602248
199 + 31602049 = 31602248
367 + 31601881 = 31602248
439 + 31601809 = 31602248
541 + 31601707 = 31602248
577 + 31601671 = 31602248

Showing the first eight; more decompositions exist.
