Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592870, here are decompositions:

37 + 31592833 = 31592870
61 + 31592809 = 31592870
73 + 31592797 = 31592870
97 + 31592773 = 31592870
109 + 31592761 = 31592870
193 + 31592677 = 31592870
229 + 31592641 = 31592870
271 + 31592599 = 31592870

Showing the first eight; more decompositions exist.
