Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540792, here are decompositions:

5 + 31540787 = 31540792
83 + 31540709 = 31540792
113 + 31540679 = 31540792
149 + 31540643 = 31540792
263 + 31540529 = 31540792
293 + 31540499 = 31540792
449 + 31540343 = 31540792
683 + 31540109 = 31540792

Showing the first eight; more decompositions exist.
