Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528942, here are decompositions:

89 + 31528853 = 31528942
101 + 31528841 = 31528942
131 + 31528811 = 31528942
191 + 31528751 = 31528942
383 + 31528559 = 31528942
443 + 31528499 = 31528942
491 + 31528451 = 31528942
509 + 31528433 = 31528942

Showing the first eight; more decompositions exist.
