Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540612, here are decompositions:

83 + 31540529 = 31540612
113 + 31540499 = 31540612
269 + 31540343 = 31540612
401 + 31540211 = 31540612
431 + 31540181 = 31540612
449 + 31540163 = 31540612
503 + 31540109 = 31540612
599 + 31540013 = 31540612

Showing the first eight; more decompositions exist.
