Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601190, here are decompositions:

11 + 31601179 = 31601190
53 + 31601137 = 31601190
107 + 31601083 = 31601190
113 + 31601077 = 31601190
139 + 31601051 = 31601190
149 + 31601041 = 31601190
167 + 31601023 = 31601190
197 + 31600993 = 31601190

Showing the first eight; more decompositions exist.
