Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554104, here are decompositions:

31 + 31554073 = 31554104
61 + 31554043 = 31554104
271 + 31553833 = 31554104
397 + 31553707 = 31554104
433 + 31553671 = 31554104
487 + 31553617 = 31554104
577 + 31553527 = 31554104
601 + 31553503 = 31554104

Showing the first eight; more decompositions exist.
