Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619044, here are decompositions:

3 + 31619041 = 31619044
53 + 31618991 = 31619044
101 + 31618943 = 31619044
173 + 31618871 = 31619044
263 + 31618781 = 31619044
293 + 31618751 = 31619044
641 + 31618403 = 31619044
683 + 31618361 = 31619044

Showing the first eight; more decompositions exist.
