Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601186, here are decompositions:

7 + 31601179 = 31601186
103 + 31601083 = 31601186
109 + 31601077 = 31601186
163 + 31601023 = 31601186
193 + 31600993 = 31601186
229 + 31600957 = 31601186
433 + 31600753 = 31601186
523 + 31600663 = 31601186

Showing the first eight; more decompositions exist.
