Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538202, here are decompositions:

41 + 31538161 = 31538202
61 + 31538141 = 31538202
71 + 31538131 = 31538202
89 + 31538113 = 31538202
131 + 31538071 = 31538202
139 + 31538063 = 31538202
149 + 31538053 = 31538202
173 + 31538029 = 31538202

Showing the first eight; more decompositions exist.
