Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90142, here are decompositions:

53 + 90089 = 90142
71 + 90071 = 90142
83 + 90059 = 90142
89 + 90053 = 90142
131 + 90011 = 90142
179 + 89963 = 90142
233 + 89909 = 90142
251 + 89891 = 90142

Showing the first eight; more decompositions exist.
