Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592912, here are decompositions:

79 + 31592833 = 31592912
103 + 31592809 = 31592912
139 + 31592773 = 31592912
151 + 31592761 = 31592912
229 + 31592683 = 31592912
271 + 31592641 = 31592912
313 + 31592599 = 31592912
523 + 31592389 = 31592912

Showing the first eight; more decompositions exist.
