Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492382, here are decompositions:

13 + 31492369 = 31492382
139 + 31492243 = 31492382
331 + 31492051 = 31492382
349 + 31492033 = 31492382
541 + 31491841 = 31492382
769 + 31491613 = 31492382
811 + 31491571 = 31492382
1051 + 31491331 = 31492382

Showing the first eight; more decompositions exist.
