Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554612, here are decompositions:

29 + 31554583 = 31554612
41 + 31554571 = 31554612
43 + 31554569 = 31554612
71 + 31554541 = 31554612
73 + 31554539 = 31554612
101 + 31554511 = 31554612
139 + 31554473 = 31554612
149 + 31554463 = 31554612

Showing the first eight; more decompositions exist.
