Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492954, here are decompositions:

31 + 2147492923 = 2147492954
283 + 2147492671 = 2147492954
421 + 2147492533 = 2147492954
433 + 2147492521 = 2147492954
463 + 2147492491 = 2147492954
601 + 2147492353 = 2147492954
1051 + 2147491903 = 2147492954
1117 + 2147491837 = 2147492954

Showing the first eight; more decompositions exist.
