Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554610, here are decompositions:

41 + 31554569 = 31554610
71 + 31554539 = 31554610
83 + 31554527 = 31554610
137 + 31554473 = 31554610
431 + 31554179 = 31554610
449 + 31554161 = 31554610
467 + 31554143 = 31554610
599 + 31554011 = 31554610

Showing the first eight; more decompositions exist.
