Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554132, here are decompositions:

11 + 31554121 = 31554132
59 + 31554073 = 31554132
89 + 31554043 = 31554132
139 + 31553993 = 31554132
149 + 31553983 = 31554132
229 + 31553903 = 31554132
331 + 31553801 = 31554132
349 + 31553783 = 31554132

Showing the first eight; more decompositions exist.
