Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523154, here are decompositions:

11 + 31523143 = 31523154
23 + 31523131 = 31523154
41 + 31523113 = 31523154
43 + 31523111 = 31523154
73 + 31523081 = 31523154
101 + 31523053 = 31523154
127 + 31523027 = 31523154
151 + 31523003 = 31523154

Showing the first eight; more decompositions exist.
