Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541684, here are decompositions:

7 + 31541677 = 31541684
73 + 31541611 = 31541684
103 + 31541581 = 31541684
127 + 31541557 = 31541684
157 + 31541527 = 31541684
283 + 31541401 = 31541684
337 + 31541347 = 31541684
523 + 31541161 = 31541684

Showing the first eight; more decompositions exist.
