Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540132, here are decompositions:

23 + 31540109 = 31540132
101 + 31540031 = 31540132
269 + 31539863 = 31540132
293 + 31539839 = 31540132
311 + 31539821 = 31540132
419 + 31539713 = 31540132
461 + 31539671 = 31540132
563 + 31539569 = 31540132

Showing the first eight; more decompositions exist.
