Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540324, here are decompositions:

83 + 31540241 = 31540324
107 + 31540217 = 31540324
113 + 31540211 = 31540324
293 + 31540031 = 31540324
311 + 31540013 = 31540324
317 + 31540007 = 31540324
353 + 31539971 = 31540324
461 + 31539863 = 31540324

Showing the first eight; more decompositions exist.
