Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619332, here are decompositions:

5 + 31619327 = 31619332
71 + 31619261 = 31619332
149 + 31619183 = 31619332
383 + 31618949 = 31619332
389 + 31618943 = 31619332
431 + 31618901 = 31619332
449 + 31618883 = 31619332
461 + 31618871 = 31619332

Showing the first eight; more decompositions exist.
