Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31505048, here are decompositions:

61 + 31504987 = 31505048
67 + 31504981 = 31505048
97 + 31504951 = 31505048
139 + 31504909 = 31505048
229 + 31504819 = 31505048
397 + 31504651 = 31505048
457 + 31504591 = 31505048
661 + 31504387 = 31505048

Showing the first eight; more decompositions exist.
