Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554202, here are decompositions:

3 + 31554199 = 31554202
23 + 31554179 = 31554202
41 + 31554161 = 31554202
59 + 31554143 = 31554202
191 + 31554011 = 31554202
401 + 31553801 = 31554202
419 + 31553783 = 31554202
443 + 31553759 = 31554202

Showing the first eight; more decompositions exist.
