Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594220, here are decompositions:

61 + 31594159 = 31594220
139 + 31594081 = 31594220
157 + 31594063 = 31594220
181 + 31594039 = 31594220
277 + 31593943 = 31594220
283 + 31593937 = 31594220
433 + 31593787 = 31594220
457 + 31593763 = 31594220

Showing the first eight; more decompositions exist.
