Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493492, here are decompositions:

73 + 31493419 = 31493492
139 + 31493353 = 31493492
241 + 31493251 = 31493492
409 + 31493083 = 31493492
439 + 31493053 = 31493492
463 + 31493029 = 31493492
571 + 31492921 = 31493492
643 + 31492849 = 31493492

Showing the first eight; more decompositions exist.
