Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619632, here are decompositions:

29 + 31619603 = 31619632
71 + 31619561 = 31619632
89 + 31619543 = 31619632
101 + 31619531 = 31619632
113 + 31619519 = 31619632
131 + 31619501 = 31619632
173 + 31619459 = 31619632
419 + 31619213 = 31619632

Showing the first eight; more decompositions exist.
