Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619502, here are decompositions:

43 + 31619459 = 31619502
113 + 31619389 = 31619502
191 + 31619311 = 31619502
241 + 31619261 = 31619502
293 + 31619209 = 31619502
311 + 31619191 = 31619502
331 + 31619171 = 31619502
359 + 31619143 = 31619502

Showing the first eight; more decompositions exist.
