Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592904, here are decompositions:

61 + 31592843 = 31592904
71 + 31592833 = 31592904
107 + 31592797 = 31592904
131 + 31592773 = 31592904
157 + 31592747 = 31592904
227 + 31592677 = 31592904
241 + 31592663 = 31592904
263 + 31592641 = 31592904

Showing the first eight; more decompositions exist.
