Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542542, here are decompositions:

19 + 31542523 = 31542542
103 + 31542439 = 31542542
151 + 31542391 = 31542542
313 + 31542229 = 31542542
379 + 31542163 = 31542542
439 + 31542103 = 31542542
541 + 31542001 = 31542542
571 + 31541971 = 31542542

Showing the first eight; more decompositions exist.
