Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535448, here are decompositions:

19 + 31535429 = 31535448
29 + 31535419 = 31535448
31 + 31535417 = 31535448
37 + 31535411 = 31535448
67 + 31535381 = 31535448
71 + 31535377 = 31535448
107 + 31535341 = 31535448
127 + 31535321 = 31535448

Showing the first eight; more decompositions exist.
