Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506350, here are decompositions:

19 + 31506331 = 31506350
67 + 31506283 = 31506350
79 + 31506271 = 31506350
103 + 31506247 = 31506350
157 + 31506193 = 31506350
367 + 31505983 = 31506350
541 + 31505809 = 31506350
613 + 31505737 = 31506350

Showing the first eight; more decompositions exist.
