Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613502, here are decompositions:

61 + 31613441 = 31613502
101 + 31613401 = 31613502
103 + 31613399 = 31613502
211 + 31613291 = 31613502
311 + 31613191 = 31613502
331 + 31613171 = 31613502
359 + 31613143 = 31613502
383 + 31613119 = 31613502

Showing the first eight; more decompositions exist.
