Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493102, here are decompositions:

19 + 31493083 = 31493102
73 + 31493029 = 31493102
139 + 31492963 = 31493102
181 + 31492921 = 31493102
331 + 31492771 = 31493102
439 + 31492663 = 31493102
499 + 31492603 = 31493102
631 + 31492471 = 31493102

Showing the first eight; more decompositions exist.
