Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619482, here are decompositions:

23 + 31619459 = 31619482
269 + 31619213 = 31619482
311 + 31619171 = 31619482
353 + 31619129 = 31619482
359 + 31619123 = 31619482
491 + 31618991 = 31619482
599 + 31618883 = 31619482
659 + 31618823 = 31619482

Showing the first eight; more decompositions exist.
