Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480242, here are decompositions:

41 + 31480201 = 31480242
113 + 31480129 = 31480242
139 + 31480103 = 31480242
151 + 31480091 = 31480242
163 + 31480079 = 31480242
181 + 31480061 = 31480242
193 + 31480049 = 31480242
223 + 31480019 = 31480242

Showing the first eight; more decompositions exist.
