Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554060, here are decompositions:

17 + 31554043 = 31554060
47 + 31554013 = 31554060
67 + 31553993 = 31554060
73 + 31553987 = 31554060
157 + 31553903 = 31554060
193 + 31553867 = 31554060
227 + 31553833 = 31554060
257 + 31553803 = 31554060

Showing the first eight; more decompositions exist.
