Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619038, here are decompositions:

29 + 31619009 = 31619038
47 + 31618991 = 31619038
89 + 31618949 = 31619038
137 + 31618901 = 31619038
167 + 31618871 = 31619038
257 + 31618781 = 31619038
401 + 31618637 = 31619038
491 + 31618547 = 31619038

Showing the first eight; more decompositions exist.
