Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588762, here are decompositions:

53 + 31588709 = 31588762
83 + 31588679 = 31588762
89 + 31588673 = 31588762
131 + 31588631 = 31588762
239 + 31588523 = 31588762
269 + 31588493 = 31588762
431 + 31588331 = 31588762
449 + 31588313 = 31588762

Showing the first eight; more decompositions exist.
