Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554504, here are decompositions:

11 + 31554493 = 31554504
31 + 31554473 = 31554504
41 + 31554463 = 31554504
71 + 31554433 = 31554504
103 + 31554401 = 31554504
167 + 31554337 = 31554504
263 + 31554241 = 31554504
383 + 31554121 = 31554504

Showing the first eight; more decompositions exist.
