Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540276, here are decompositions:

59 + 31540217 = 31540276
113 + 31540163 = 31540276
167 + 31540109 = 31540276
263 + 31540013 = 31540276
269 + 31540007 = 31540276
419 + 31539857 = 31540276
563 + 31539713 = 31540276
569 + 31539707 = 31540276

Showing the first eight; more decompositions exist.
