Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540632, here are decompositions:

59 + 31540573 = 31540632
103 + 31540529 = 31540632
131 + 31540501 = 31540632
139 + 31540493 = 31540632
191 + 31540441 = 31540632
269 + 31540363 = 31540632
293 + 31540339 = 31540632
419 + 31540213 = 31540632

Showing the first eight; more decompositions exist.
