Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522542, here are decompositions:

13 + 31522529 = 31522542
19 + 31522523 = 31522542
83 + 31522459 = 31522542
101 + 31522441 = 31522542
109 + 31522433 = 31522542
131 + 31522411 = 31522542
179 + 31522363 = 31522542
211 + 31522331 = 31522542

Showing the first eight; more decompositions exist.
