Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554356, here are decompositions:

19 + 31554337 = 31554356
73 + 31554283 = 31554356
157 + 31554199 = 31554356
193 + 31554163 = 31554356
283 + 31554073 = 31554356
313 + 31554043 = 31554356
373 + 31553983 = 31554356
523 + 31553833 = 31554356

Showing the first eight; more decompositions exist.
