Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540294, here are decompositions:

53 + 31540241 = 31540294
83 + 31540211 = 31540294
113 + 31540181 = 31540294
131 + 31540163 = 31540294
263 + 31540031 = 31540294
281 + 31540013 = 31540294
431 + 31539863 = 31540294
557 + 31539737 = 31540294

Showing the first eight; more decompositions exist.
