Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463532, here are decompositions:

5 + 31463527 = 31463532
13 + 31463519 = 31463532
43 + 31463489 = 31463532
73 + 31463459 = 31463532
103 + 31463429 = 31463532
179 + 31463353 = 31463532
211 + 31463321 = 31463532
251 + 31463281 = 31463532

Showing the first eight; more decompositions exist.
