Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540426, here are decompositions:

83 + 31540343 = 31540426
263 + 31540163 = 31540426
317 + 31540109 = 31540426
419 + 31540007 = 31540426
563 + 31539863 = 31540426
569 + 31539857 = 31540426
587 + 31539839 = 31540426
719 + 31539707 = 31540426

Showing the first eight; more decompositions exist.
