Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493234, here are decompositions:

43 + 31493191 = 31493234
103 + 31493131 = 31493234
151 + 31493083 = 31493234
181 + 31493053 = 31493234
271 + 31492963 = 31493234
313 + 31492921 = 31493234
397 + 31492837 = 31493234
433 + 31492801 = 31493234

Showing the first eight; more decompositions exist.
