Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541174, here are decompositions:

13 + 31541161 = 31541174
61 + 31541113 = 31541174
73 + 31541101 = 31541174
103 + 31541071 = 31541174
127 + 31541047 = 31541174
157 + 31541017 = 31541174
307 + 31540867 = 31541174
337 + 31540837 = 31541174

Showing the first eight; more decompositions exist.
