Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592922, here are decompositions:

73 + 31592849 = 31592922
79 + 31592843 = 31592922
89 + 31592833 = 31592922
113 + 31592809 = 31592922
149 + 31592773 = 31592922
239 + 31592683 = 31592922
271 + 31592651 = 31592922
281 + 31592641 = 31592922

Showing the first eight; more decompositions exist.
