Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548002, here are decompositions:

43 + 31547959 = 31548002
151 + 31547851 = 31548002
163 + 31547839 = 31548002
271 + 31547731 = 31548002
331 + 31547671 = 31548002
373 + 31547629 = 31548002
463 + 31547539 = 31548002
523 + 31547479 = 31548002

Showing the first eight; more decompositions exist.
