Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554502, here are decompositions:

29 + 31554473 = 31554502
53 + 31554449 = 31554502
101 + 31554401 = 31554502
359 + 31554143 = 31554502
491 + 31554011 = 31554502
509 + 31553993 = 31554502
599 + 31553903 = 31554502
701 + 31553801 = 31554502

Showing the first eight; more decompositions exist.
