Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493632, here are decompositions:

59 + 31493573 = 31493632
113 + 31493519 = 31493632
293 + 31493339 = 31493632
311 + 31493321 = 31493632
383 + 31493249 = 31493632
431 + 31493201 = 31493632
461 + 31493171 = 31493632
479 + 31493153 = 31493632

Showing the first eight; more decompositions exist.
