Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452174, here are decompositions:

37 + 31452137 = 31452174
43 + 31452131 = 31452174
53 + 31452121 = 31452174
113 + 31452061 = 31452174
167 + 31452007 = 31452174
181 + 31451993 = 31452174
293 + 31451881 = 31452174
317 + 31451857 = 31452174

Showing the first eight; more decompositions exist.
