Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1492, here are decompositions:

3 + 1489 = 1492
5 + 1487 = 1492
11 + 1481 = 1492
41 + 1451 = 1492
53 + 1439 = 1492
59 + 1433 = 1492
83 + 1409 = 1492
131 + 1361 = 1492

Showing the first eight; more decompositions exist.
