Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496462, here are decompositions:

13 + 31496449 = 31496462
43 + 31496419 = 31496462
73 + 31496389 = 31496462
199 + 31496263 = 31496462
241 + 31496221 = 31496462
379 + 31496083 = 31496462
421 + 31496041 = 31496462
541 + 31495921 = 31496462

Showing the first eight; more decompositions exist.
