Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33587142, here are decompositions:

31 + 33587111 = 33587142
53 + 33587089 = 33587142
103 + 33587039 = 33587142
131 + 33587011 = 33587142
151 + 33586991 = 33587142
263 + 33586879 = 33587142
313 + 33586829 = 33587142
431 + 33586711 = 33587142

Showing the first eight; more decompositions exist.
