Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619098, here are decompositions:

89 + 31619009 = 31619098
107 + 31618991 = 31619098
149 + 31618949 = 31619098
197 + 31618901 = 31619098
227 + 31618871 = 31619098
317 + 31618781 = 31619098
347 + 31618751 = 31619098
461 + 31618637 = 31619098

Showing the first eight; more decompositions exist.
