Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542586, here are decompositions:

107 + 31542479 = 31542586
149 + 31542437 = 31542586
167 + 31542419 = 31542586
227 + 31542359 = 31542586
263 + 31542323 = 31542586
353 + 31542233 = 31542586
389 + 31542197 = 31542586
503 + 31542083 = 31542586

Showing the first eight; more decompositions exist.
