Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540090, here are decompositions:

59 + 31540031 = 31540090
83 + 31540007 = 31540090
227 + 31539863 = 31540090
233 + 31539857 = 31540090
251 + 31539839 = 31540090
269 + 31539821 = 31540090
353 + 31539737 = 31540090
383 + 31539707 = 31540090

Showing the first eight; more decompositions exist.
