Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90542, here are decompositions:

13 + 90529 = 90542
19 + 90523 = 90542
31 + 90511 = 90542
43 + 90499 = 90542
61 + 90481 = 90542
73 + 90469 = 90542
103 + 90439 = 90542
139 + 90403 = 90542

Showing the first eight; more decompositions exist.
