Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548194, here are decompositions:

61 + 31548133 = 31548194
163 + 31548031 = 31548194
241 + 31547953 = 31548194
277 + 31547917 = 31548194
463 + 31547731 = 31548194
487 + 31547707 = 31548194
523 + 31547671 = 31548194
577 + 31547617 = 31548194

Showing the first eight; more decompositions exist.
