Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554232, here are decompositions:

53 + 31554179 = 31554232
71 + 31554161 = 31554232
89 + 31554143 = 31554232
239 + 31553993 = 31554232
431 + 31553801 = 31554232
449 + 31553783 = 31554232
503 + 31553729 = 31554232
569 + 31553663 = 31554232

Showing the first eight; more decompositions exist.
