Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554532, here are decompositions:

5 + 31554527 = 31554532
59 + 31554473 = 31554532
83 + 31554449 = 31554532
131 + 31554401 = 31554532
353 + 31554179 = 31554532
389 + 31554143 = 31554532
521 + 31554011 = 31554532
773 + 31553759 = 31554532

Showing the first eight; more decompositions exist.
