Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500452, here are decompositions:

73 + 31500379 = 31500452
463 + 31499989 = 31500452
619 + 31499833 = 31500452
691 + 31499761 = 31500452
853 + 31499599 = 31500452
859 + 31499593 = 31500452
1021 + 31499431 = 31500452
1051 + 31499401 = 31500452

Showing the first eight; more decompositions exist.
