Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498574, here are decompositions:

61 + 31498513 = 31498574
103 + 31498471 = 31498574
463 + 31498111 = 31498574
487 + 31498087 = 31498574
571 + 31498003 = 31498574
577 + 31497997 = 31498574
643 + 31497931 = 31498574
691 + 31497883 = 31498574

Showing the first eight; more decompositions exist.
