Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540462, here are decompositions:

251 + 31540211 = 31540462
281 + 31540181 = 31540462
353 + 31540109 = 31540462
431 + 31540031 = 31540462
449 + 31540013 = 31540462
491 + 31539971 = 31540462
599 + 31539863 = 31540462
641 + 31539821 = 31540462

Showing the first eight; more decompositions exist.
