Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619684, here are decompositions:

37 + 31619647 = 31619684
67 + 31619617 = 31619684
73 + 31619611 = 31619684
127 + 31619557 = 31619684
157 + 31619527 = 31619684
163 + 31619521 = 31619684
277 + 31619407 = 31619684
373 + 31619311 = 31619684

Showing the first eight; more decompositions exist.
