Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493192, here are decompositions:

61 + 31493131 = 31493192
109 + 31493083 = 31493192
139 + 31493053 = 31493192
163 + 31493029 = 31493192
229 + 31492963 = 31493192
271 + 31492921 = 31493192
421 + 31492771 = 31493192
541 + 31492651 = 31493192

Showing the first eight; more decompositions exist.
