Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85742, here are decompositions:

31 + 85711 = 85742
73 + 85669 = 85742
103 + 85639 = 85742
193 + 85549 = 85742
211 + 85531 = 85742
229 + 85513 = 85742
313 + 85429 = 85742
331 + 85411 = 85742

Showing the first eight; more decompositions exist.
