Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492532, here are decompositions:

3 + 31492529 = 31492532
61 + 31492471 = 31492532
79 + 31492453 = 31492532
103 + 31492429 = 31492532
109 + 31492423 = 31492532
139 + 31492393 = 31492532
163 + 31492369 = 31492532
271 + 31492261 = 31492532

Showing the first eight; more decompositions exist.
