Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535732, here are decompositions:

61 + 31535671 = 31535732
139 + 31535593 = 31535732
181 + 31535551 = 31535732
229 + 31535503 = 31535732
313 + 31535419 = 31535732
421 + 31535311 = 31535732
499 + 31535233 = 31535732
601 + 31535131 = 31535732

Showing the first eight; more decompositions exist.
