Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493396, here are decompositions:

19 + 31493377 = 31493396
43 + 31493353 = 31493396
73 + 31493323 = 31493396
313 + 31493083 = 31493396
349 + 31493047 = 31493396
367 + 31493029 = 31493396
379 + 31493017 = 31493396
433 + 31492963 = 31493396

Showing the first eight; more decompositions exist.
