Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463542, here are decompositions:

23 + 31463519 = 31463542
53 + 31463489 = 31463542
59 + 31463483 = 31463542
83 + 31463459 = 31463542
113 + 31463429 = 31463542
179 + 31463363 = 31463542
281 + 31463261 = 31463542
293 + 31463249 = 31463542

Showing the first eight; more decompositions exist.
