Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619104, here are decompositions:

113 + 31618991 = 31619104
233 + 31618871 = 31619104
281 + 31618823 = 31619104
353 + 31618751 = 31619104
401 + 31618703 = 31619104
467 + 31618637 = 31619104
557 + 31618547 = 31619104
641 + 31618463 = 31619104

Showing the first eight; more decompositions exist.
